test(archsetup): fix fixture scope and initramfs path in the sweep

VM run #2 exposed two test bugs (archsetup itself passed clean, 53/0/0):

- ScopeMismatch errors on 26 tests: the host-dependent fixtures were
  session-scoped, but Testinfra's host fixture is module-scoped, and a
  session fixture cannot request a module one. Drop those fixtures to
  module scope.

- test_console_font_in_initramfs hardcoded /boot/initramfs-linux.img; this
  fleet runs linux-lts, so the image is initramfs-linux-lts.img. Pick the
  main (non-fallback) initramfs by glob instead.
