Subject: make: Support CPPFLAGS in Makefile

Currently Makefile ignores CPPFLAGS and so any defines passed via
environment/command line ignored. E.g. running

  make CPPFLAGS="-D_FORTIFY_SOURCE=2"

does not compile llmnrd with buffer overflow checks.

Fix it by considering CPPFLAGS in the Makefile and appending them to
CFLAGS.

Closes #17
