Implement support for enable_backup CONFIG value.

The enable_backup CONFIG value can be used to generate deployment
for backup registration file for an application.

BACKUP_REGISTRATION_FILE_SYMBIAN and BACKUP_REGISTRATION_FILE_MAEMO
variables can be used to specify a custom backup registration files.

Only works on Symbian and Maemo platforms.
