[meta-fsl-arm][PATCH 2/3] pulseaudio: Fix mutext issue when do pause in gstreamer

[Jun Zhu <R01007@freescale.com>]

Pulseaudio crashes when other program using sound:
Assertion 'pthread_mutex_unlock(&m->mutex) == 0' failed
at pulsecore/mutex-posix.c:106, function pa_mutex_unlock().

Disable PTHREAD priority inheritance feature is the easiest
workaround solutions for this issue.
