[PATCH 1/2] wrapper.c: remove unused git_mkstemp() function

[PATCH 1/2] wrapper.c: remove unused git_mkstemp() function

[Ramsay Jones]

The last caller of git_mkstemp() was removed in commit 6fec0a89
("verify_signed_buffer: use tempfile object", 16-06-2016). Since
the introduction of the 'tempfile' APIs, along with git_mkstemp_mode,
it is unlikely that new callers will materialize. Remove the dead
code.

Yeah, I think the tempfile API is a better choice for anybody who wants
to add a new call. Removing the temptation (and the dead code) is a good
move.
