imlib2: Upgrade 1.7.1 -> 1.12.1

Upgrade to version 1.12.1:

- Fix some clang complaints
- scaling: MMX asm scaling causes segv, disable for now
- loading: Call module exit function also when not dlclosing
  module on unload
- loaders: Fix build with -m32 --enable-debug
- RAW loader: Don't unload loader
- imlib2_grab, imlib2_view: Unset context colormap
- x11_grab: Use correct depth when grabbing

Remove bzip2 from PACKAGECONFIG because for this version it is an
unrecognised option.
