res_stasis_snoop: Spying on a single direction continually increases CPU

Creating a snoop channel in ARI and spying only on a single direction (in or
out) results in CPU utilization continually increasing until the CPU is fully
consumed. This occurs because frames are being put in the opposing direction's
slin factory queue, but not being removed.

Fixed the problem by setting a new flag on audiohook initialization that
specifies whether or not to make the audiohook read or write only. If set
no frames are written to the associated factory queue.
