ISSUE DESCRIPTION
===
Guest tests shouldn't care about the capabilities or firmware of the
underlying hosts, so drop the request of specific freebsd-
hostflags for FreeBSD guest tests.
While there request the presence of the hvm hostflag since the FreeBSD
guest tests are run in HVM mode.

There are multiple errors with the handling of these three MSRs, but they are
deliberately not addressed this point.
This removes the dance converting -1/0/1 into X86EMUL_*, allowing for the
removal of the 'ret' variable.

This removes some nondeterminism from the output.

Specifically, we narrow the initial query to flights which have at
least some job with the built_revision_foo we are looking for.
This condition is strictly broader than that implemented inside the
flight search loop, so there is no functional change.
Perf: runtime of my test case now ~300s-500s.
$jcheckq is redundant: we looked this up right at the start.
This is not expected to speed things up very much, but it makes things
somewhat cleaner and clearer.

Our spec. says we return nulls for started and status if we don't find

Stuff the two queries together: we use the firsty query as a WITH

Right now this is pointless since the Perl code doesn't need it. But
this row is going to be part of a WITH clause soon.
