Make valgrind optional

Some platforms don't have valgrind support, and sometimes you simply might
not want to use valgrind.  But at present, dtc, or more specifically its
testsuite, won't compile without valgrind because we use the valgrind
client interface in some places to improve our testing and suppress false
positives.

This adds some Makefile detection to correctly handle the case where
valgrind is not available.
