tests: read-print: Update expectations.

This follows up on commit 974b04ab8063382f3a91b0cf5e46bac6e0238672, which
I tested with the wrong test (tests/style.scm) instead.  Oops.

* gnu/packages/code.scm (astyle): Update to 3.4.8.
[arguments]: Don't explicitly return #t from phases.

read-print: Be more mindful of horizontal space in packages.

Perhaps due to their staged nature, packages tend to be ‘lopsided’: deeply
nested, with the most elaborate code on the {build,right-hand-,in}side, in
snippets and phases.

When we indent outer forms too eagerly, we can easily run short on
columns by the time we get to the build code, reducing readability.  A
few strategically-placed newlines early on can make a big difference.

* guix/read-print.scm (%newline-forms): Add a newline after opening a
<package> source field or an argument list.  Compensate by removing the
base32 special case, which is now unnecessary.

gnu: python-pyusb: Add libusb-compat backend.

* gnu/packages/libusb.scm (python-pyusb) <arguments>: Do not hard-code
  libusb1 library for all back-ends, and allow to use libusb0 as a
  back-end.  Also enabled tests as the package does have a test suite.
