radix tree test suite: Remove duplicate bitops code
...
By adding __set_bit and __clear_bit to the tools include directory, we
can share the bitops code. This reveals an include loop between kernel.h,
log2.h, bitmap.h and bitops.h. Break it the same way as the kernel does;
by moving the kernel.h include from bitops.h to bitmap.h.

tools: Remove bitops/hweight usage of bits in tools/perf
...
We need to use lib/hweight.c for that, just like we do for lib/rbtree.c,
so tools need to link hweight.o. For now do it directly, but we need to
have a tools/lib/lk.a or .so that collects these goodies...

So that we better mirror the kernel sources and make it available for
other tools.
