Allow profman to resolve symlinks on dirs

When opening the dex files we sometime need to check for the real location
of the file (even if it was open via an fd).

Denial example:

avc: denied { getattr } for comm="profman" path="/data/app" dev="sda13"
ino=1048577 scontext=u:r:profman:s0 tcontext=u:object_r:apk_data_file:s0
tclass=dir permissive=0

Test: verify we get no denials when taking a profile snapshot.
