allow committing transaction without a lock file

This is useful to allow front-ends to manage the lock file themselves,
allowing them to ensure database consistency across multiple commands, e.g.:

 paclock --lock
 pacinstall --no-lock foo
 # foo is guaranteed to be installed until the db is unlocked
 paclock --unlock
