When installd clears cached files on external storage, the sdcardfs
kernel filesystem needs to be kept in the loop to release any cached
dentries that it's holding onto.  (Otherwise the underlying disk
space isn't actually released.)

installd can already delete the underlying files directly (via the
media_rw_data_file rules), so this technically isn't expanding its
capabilities.

Adding the default label/mapping is important because:
1.  Lookups of services without an selinux label should generate
    a denial.
2.  In permissive mode, lookups of a service without a label should be
    be allowed, without the default label service manager disallows
    access.
3.  We can neverallow use of the default label.

Bug: 37762790
Test: Build and flash policy onto Marlin with unlabeled vendor services.
    Add/find of unlabeled vendor services generate a denial.
