serializer: set output name to .serialized

By default libdbuspolicy may expect serialized policy file
in default location, with XML policy file name modified
by adding .serialized suffix.

This changes serializer default behavior to create output files
with the same naming rules instead of using result.dat.

Of course, if a user specifies its own specific output file name,
the serializer still creates output file with the given name.
