mailmap.c: fix a memory leak in free_mailap_{info,entry}() 

In the free_mailmap_entry() code added in 0925ce4d49 (Add map_user()
and clear_mailmap() to mailmap, 2009-02-08) the intent was clearly to
clear the "me" structure, but while we freed parts of the
mailmap_entry structure, we didn't free the structure itself. The same
goes for the "mailmap_info" structure.

This brings the number of SANITIZE=leak failures in t4203-mailmap.sh
down from 50 to 49. Not really progress as far as the number of
failures is concerned, but as far as I can tell this fixes all leaks
in mailmap.c itself. There's still users of it such as builtin/log.c
that call read_mailmap() without a clear_mailmap(), but that's on
them.
