BackupManagerService files need new security labeling.

Use restorecon to label files and directories
specific to BMS.

 * /data/backup : provide default type labeling
    for all files/dirs used by BMS.

 * /data/secure/backup : provide default type
    labeling used by BMS when encrypted
    file system is enabled.

 * /cache/<package name>.{data|restore} :
    specifically target files opened and
    passed by BMS to apps that have backup
    capabilities.

 * /cache/backup : default labeling for the
    directory used by the LocalTransport
    that stores backup files for local testing.
