perf tools: Fill in new definitions for madvise()/mmap() flags

builtin-trace.c started using various new syscall features not defined
in the header files of older distros - resulting in build failures.

Fill in the (ABI) constants if they are not defined.

(There might be a better place to put this than builtin-trace.c, into a
compat header or so.)
