Allow mpdecision dac_override.

Addresses denials such as:
avc: denied { dac_override } for comm="mpdecision" capability=1 scontext=u:r:mpdecision:s0 tcontext=u:r:mpdecision:s0 tclass=capability

Also auditallow them so that we can track its usage and hopefully
eliminate the need for this capability in the future.
