[StGIT PATCH 3/5] Remove an unnecessary parameter to make_patch_name

["Karl Hasselström" <kha@treskal.com>]

From: Karl Hasselström <kha@treskal.com>

The "alternative" parameter was a boolean that indicated whether we
were interested in testing if the first generated name was acceptable,
or if we would just always accept it. But that can be accomplished by
giving an "unacceptable" function that always returns False, so
there's no need for an additional parameter.
