installer: services: Disable desktop page on Hurd and 32-bit x86.

To prevent confusion, remove possibility to choose the desktop services on
both Hurd and 32-bit x86. As the info text suggests, desktop environments are not
available on Hurd. As for x86, there some of the services do not build. While
it is more idiomatic to fix those services, for the 1.5.0 release, use this
workaround to disable the desktop page. This ensures users aren't left
building something that will fail.

* gnu/installer/newt/services.scm
(run-desktop-environments-cbt-page): No longer show special info on Hurd.
(run-desktop-environments-cbt-page/maybe): Call
run-desktop-environments-cbt-page on architectures that support desktop
environments well.

install: Add guix-system-installer executable to system profile.

To allow users in headless consoles to use the graphical installer, add an

in headless setups will get to know about it.

install: Show different motd in headless console.

motd is shown by the pam module, it doesn't support changing what motd gets
displayed easily. The only way to control it is by read permissions on
individual motd files, making files unreadable by the user logging in.

So instead of that, make a custom script that prints different motd,
checking if a temporary file exists. An environment variable would be better
suited for this purpose, but those aren't passed through by PAM.

* gnu/system/install.scm
(%installation-login-pam-service): New variable. Modified login pam service.
(%installation-console-login): New variable. Wrapper around login to create a
file for PAM rule.
(%installation-services): Use new login pam service and wrapper.

install: Register agetty on primary console on AArch64.

This adds the possibility to parse /proc/consoles to find a primary console.
Then, on AArch64 this is used in the installation image. On AArch64, the boot
usually happens with chosen device tree that contains the serial console.
On x86_64, this does not happen so often, so we keep the installation iso
minimal there.

The primary console is chosen, but there is a fallback to any non-virtual one.
Virtual console (/dev/tty0) is skipped, because that one can point to any
console, like /dev/tty1 and so on. So it's not safe to register agetty on it.

* gnu/build/linux-boot.scm (read-linux-consoles): New variable.
* gnu/services/base.scm (default-serial-console): Use primary console as
fallback.
* gnu/system/install.scm (%installation-services): Add agetty tty for
consoles.

installer: network: Check response code to assess substitute availability.

This is to accomodate following situation:
- The proxy is up
- The substitute server is down

When that happens, 5xx is returned from the proxy, typically either Bad
Gateway or Gateway Timeout. This implies the substitute server is down.

Still, for checking if the user is online, we do not check the response code.
If there is a response, even 4xx, 5xx, it still means the user is online.

* gnu/installer/newt/network.scm
(url-alive?): Add optional argument to to check the response code.
(common-urls-alive?): Add the same argument, passing it to url-alive?
(check-substitute-availability): Assume offline when non-successful http code
returned.
