Fix make install

* Uninstall didn't remove the pkg-config correctly.
* Fix `mandir`
* Allow overriding either upper- or lower-case location variables, but
  always use the lower case variables.
* Add test case that ensures overriding both upper- and lower-case
  variables is the same, and that the directory is empty after uninstall.
