valgrind: fix musl compile
Add musl libc detection (based on suggestions by Romain Naour and
Arnout Vandecappelle) and add some tweaks for musl support (based
on OpenWRT patch [1]).
Fixes ([2]):
checking the glibc version... unsupported version
configure: error: Valgrind requires glibc version 2.2 or later
Patch suggested upstream (see [3]).
