add: plug a leak on interactive_add
Plug a leak we have since
5a76aff1a6 (add: convert to use
parse_pathspec, 2013-07-14).
This leak can be triggered with:
$ git add -p anything
Fixing this leak allows us to mark as leak-free the following tests:
+ t3701-add-interactive.sh
+ t7514-commit-patch.sh
Mark them with "TEST_PASSES_SANITIZE_LEAK=true" to notice and fix
promply any new leak that may be introduced and triggered by them in the
future.
