su.te: drop domain_deprecated and app auditallow rules.

su is in permissive all the time. We don't want SELinux log
spam from this domain.

Addresses the following logspam:

  avc: granted { getattr } for comm="lsof" path="/sys/devices/virtual/graphics/fb0/vsync_event" dev="sysfs" ino=10815 scontext=u:r:su:s0 tcontext=u:object_r:sysfs:s0 tclass=file
  avc: granted { getattr } for comm="lsof" path="/sys/devices/virtual/thermal/thermal_zone2/temp" dev="sysfs" ino=15368 scontext=u:r:su:s0 tcontext=u:object_r:sysfs:s0 tclass=file
  avc: granted { read } for comm="sh" name="emmc_therm" dev="sysfs" ino=17583 scontext=u:r:su:s0 tcontext=u:object_r:sysfs:s0 tclass=file
