Subject: Fix removing empty directories

Reported by Thomas Moschny <thomas.moschny@gmx.de>:
src/patch.c (main): Temporary output files are created in the same directory as
the output file.  Make sure to remove them before removing empty files and
their empty ancestor directories; else the directories won't be empty.
tests/remove-directories: Add directory removal test case.
tests/Makefile.am (TESTS): Add new test case.
