Fix memory leaks resulting from a missing clear_pathspec().
- archive.c: Plug a leak in the "struct archiver_args", and
clear_pathspec() the "pathspec" member that the "parse_pathspec_arg()"
call in this function populates.
- builtin/clean.c: Fix a memory leak that's been with us since
893d839970 (clean: convert to use parse_pathspec, 2013-07-14).
- builtin/reset.c: Add clear_pathspec() calls to cmd_reset(),
including to the codepaths where we'd return early.
- builtin/stash.c: Call clear_pathspec() on the pathspec initialized
in push_stash().
