Add GetDsuMetadataKeyDir()
* GetDsuMetadataKeyDir() returns the metadata encryption key dir
to be used by DSU.
This function is called by libfstab during second-stage-init for
the guest DSU system to determine the userdata mount flags.
This is called by vold to clean up the key dir when removing a
DSU installation.
* DsuMetadataKeyDirFile() returns the metadata encryption key dir
indicator file. During installation, gsid (host) publish the
key dir to be used by the guest DSU system to this file.
* DefaultDsuMetadataKeyDir() returns the default key dir.
gsid calls this function to build the key dir to be used by the
guest DSU system.
* DSU metadata encryption key dir must be a subdirectory of
"/metadata/vold/metadata_encryption/dsu/".
