Test files in the same directory share the same %T. %T is easy to
misuse and cause race conditions (when running concurrently) so it has
been deprecated since D48842 (see docs/CommandGuide/lit.rst).
While here, add `rm -rf %t.dir` so that tests cannot depend on old files lying around.

This matches the behaviour of ld.bfd:

If scriptfile does not exist in the current directory, ld looks for it in
the directories specified by any preceding '-L' options. Multiple '-T'
options accumulate.
