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.)
