perf_counter: Add mmap event hooks to mprotect()
Some JIT compilers allocate memory for generated code with
posix_memalign() + mprotect() so we need to hook into mprotect()
to make sure 'perf' is aware that we're executing code in
anonymous memory.
[ penberg@cs.helsinki.fi: move the hook to sys_mprotect() ]
