tests: Add Fedora foreign distribution test.

* gnu/tests/foreign.scm (qcow-image-with-marionette):
  - Create .autorelabel file to make copied Guile work
    on SELinux-enabled systems.
(resize-lvm-xfs-partition): New variable.
(run-foreign-install-test): Increase RAM for VM to 1024
  as 512 is not sufficient to run Guix installation
  on Fedora.
(fedora-qcow2): New variable.
(%test-fedora-install): New variable.
