Grant ReadDefaultFstab() callers
allow scontext { metadata_file gsi_metadata_file_type }:dir search;
allow scontext gsi_public_metadata_file:file r_file_perms;
so they can search / read DSU metadata files.
The DSU metadata files are required to deduce the correct fstab.
Also tighten the neverallow rules in gsid.te.
