get_patch_filename(): split into two functions

The function switched between two operating modes depending on the
NULL-ness of its two parameters, as a hacky way to share small part
of implementation, sacrificing cleanliness of the API.

Implement "fmt_output_subject()" function that takes a subject
string and gives the name for the output file, and on top of it,
implement "fmt_output_commit()" function that takes a commit and
gives the name for the output file.
