[PATCH 1/2] Constify argument to make_tempname and make_tempdir

[Tom Tromey <tom at tromey dot com>]

This constifies the argument to make_tempname and make_tempdir,
removing some casts.

I initially thought that this obsoleted the allocation in
write_archive, but write_archive closes the BFD before using the name,
so this appears not to be the case.
