system: grub: Don't attempt to load non-EFI modules on EFI.

This resulted in a couple of harmless warnings just before the menu is
displayed.

* gnu/system/grub.scm (eye-candy)[setup-gfxterm-body]: Move 'vbe' and
'vga' loading to the non-EFI branch.

file-systems: Add missing docstring.

* gnu/system/file-systems.scm (file-system-type-predicate): Add
docstring.

file-systems: Do not use (gnu packages …).

Fixes a regression introduced in
7208995426714c9fc3ad59cadc3cc0f52df0f018 whereby (gnu system
file-systems) would pull in (gnu packages …) module, which in turn
breaks when importing things like (gnu build shepherd).

* gnu/system/file-systems.scm (file-system-type-predicate): Export.
(file-system-packages): Move to...
* gnu/system/linux-initrd.scm (file-system-packages): ... here.  Add
docstring.
* gnu/services/base.scm: Use it.
* tests/file-systems.scm ("does not pull (gnu packages …)"): New test.

file-systems: Factorize file-system-packages.

* gnu/system/linux-initrd.scm (base-initrd): Move helper-packages body to ...
* gnu/system/file-systems.scm (file-system-packages): ... here.  New variable.
Also export it.

Add 'guix pack'.

* gnu/system/install.scm (self-contained-tarball): Move to...
* guix/scripts/pack.scm: ... here.  New file.
* doc/guix.texi (Binary Installation): Mention 'guix pack'.
(Invoking guix pack): New node.
* build-aux/make-binary-tarball.scm: Remove.
* Makefile.am (MODULES): Add guix/scripts/pack.scm.
(EXTRA_DIST): Remove build-aux/make-binary-tarball.scm.
(guix-binary.%.tar.xz): Rewrite using 'guix pack'.
* build-aux/hydra/gnu-system.scm (tarball-jobs): Adjust accordingly.

linux-initrd: Add a raw-initrd and use it to define base-initrd.

* gnu/system/linux-initrd.scm (raw-initrd): New exported variable.
(base-initrd): Use raw-initrd to build the initrd.
* doc/guix.texi (Initial RAM Disk): Document it.

vm: Fix full-boot? option.

* gnu/system/vm.scm (virtualized-operating-system): Add full-boot?
  option. Don't add a %store-mapping when full-boot? is passed. This leads
  the grub-configuration-file procedure to look for the kernel and initrd in
  / instead of /gnu/store.
