There is a bit of a weird history here, but the net is we're not
installing python-guestfs when ENABLE_FILE_INJECTION is set, which
it is in the gate-tempest-dsvm-neutron-full-ssh job, which makes
file injection (personality) tests fail.
The history:
Commit 0ae942b41c6dcd0fe7353e7d68574194fb72a66d moved installing
python-guestfs to the hypervisor-libvirt file and it was conditional
on a flag to enable file injection and the backing distro.
Commit a3c94468baa159840a47c34cf94d97d816208313 removed the ability
to configure nova for file injection, which never made any Tempest
tests fail because we didn't have a job that tested file injection
with ssh, which is what gate-tempest-dsvm-neutron-full-ssh does.
Commit 6d3670a65280d71529f8aad8ca5a0422abffebd0 added the ability
back to enable file injection and the gate-tempest-dsvm-neutron-full-ssh
job uses it, but missed added the condition back in from 0ae942b41
which installed the python-guestfs package. This change adds that
back in.
