 Modified Files:
 	src/tests/kernel: t_mqueue.c

 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.
