allow system_server getattr on /data/dalvik-cache/profiles

86703051 wasn't complete. I thought
getattr on the directory wasn't needed but I was wrong. Not sure
how I missed this.

Addresses the following denial:

  <4>[   40.699344] type=1400 audit(15795140.469:9): avc: denied { getattr } for pid=1087 comm="system_server" path="/data/dalvik-cache/profiles" dev="mmcblk0p28" ino=105874 scontext=u:r:system_server:s0 tcontext=u:object_r:dalvikcache_profiles_data_file:s0 tclass=dir
