perf tools: Move headers check into bash script
To make it nicer and easily maintainable.
Also moving the check into fixdep sub make, so its output is not
scattered around the build output.
Removing extra $$ from mman*.h checks.

[ Use /bin/sh, and 'function check() {' -> 'check () {' to make it work with busybox, in Alpine Linux, for instance ]
