git_exec_path: avoid Coverity warning about unfree()d result

Technically, it is correct that git_exec_path() returns a possibly
malloc()ed string returned from system_path(), and it is sometimes
not allocated.  Cache the result in a static variable and make sure
that we call system_path() only once, which plugs a potential leak.
