WIP host.main_sr_uuid: don't assume $HOSTNAME is the XAPI name-label

If the host's name-label was changed using XO after installation, but the
UNIX hostname was not, $HOSTNAME is wrong.

FIXME: likely linked to flaky firstboot test, where XAPI is queried
the host before it gets initialized in the DB
