x11-misc/xscreensaver: fix compile & automagic build issues

- The RPM configure.ac change was not effective because configure was
  not being regenerated.
- Enable /proc OOM Killer detection which might not always build
  otherwise.
- Fix automagic linking against: libpng, xft, jpeg because the upstream
  configure script isn't pure autoconf:
- USE='-gdk-pixbuf -gtk -png -jpeg -opengl -xft' is now a valid
  extremely minimal build!
