oprofile: remove AX_KERNEL_VERSION from acinclude.m4

oprofile: remove AX_KERNEL_VERSION from acinclude.m4

The version of this macro in acinclude.m4 is preventing the correct
version in the package's kernelversion.m4 from being used.

Since the version in acinclude.m4 includes the obsolete config.h, any
test that uses it with newer (> 2.6.19) kernels fails.  In the case of
oprofile it means that perf_events support is never detected and thus
'legacy oprofile' is always built.

Fixing this allows the new perf_events 'operf' support to be built.
