oprofile: convert oprofile.mk to use Makefile.autotools.in and bump version

This patch bumps the version to 0.9.4 and converts the oprofile.mk to use
Makefile.autotools.in. Patches against 0.9.3 are removed since they are no
longer needed and a new patch for 0.9.4 is added.

Building for all architectures should now also be possible.
