Log Message:
PR/60002: Enji Cooper:
mq_open in FreeBSD and NetBSD both state that the path provided to the
target mqueue should (in the POSIX parlance of "should") start with a /.
In FreeBSD this proved to be more of an issue than NetBSD (especially
when `kyua debug` was involved). Instead of relying on a temp directory
which might exist outside the kyua sandbox, make the mqueue path
absolute to the prefix `/t_mqueue` (for consistency with the test), and
add the test PID to the path to avoid potential collisions between
back-to-back / concurrent test runs.

While here, explicitly cast the checked return value to `mqd_t`: this is
needed because some platforms--including FreeBSD--might define `mqd_t` as
an unsigned type instead of a signed type. Casting it to `mqd_t` helps
quell a valid compiler warning in that case.
