libselinux: add selinux_snapperd_contexts_path()

Snapper needs a way how to set a proper selinux context on btrfs
subvolumes originating in snapshot create command. Fs can't handle it on
its own so snapper will enforce .snapshots subvolume relabeling
according to a file returned by selinux_snapperd_contexts_path().

The format of the file will be similar to other contexts file:

snapperd_data = system_u:object_r:snapperd_data_t:s0
