scons: Whitelist useful environment variables
Scons normally removes all environment variables that aren't
whitelisted from the build environment. This messes up things like
ccache, distcc, and the clang static analyzer. This changeset adds the
DISTCC_, CCACHE_, and CCC_ prefixes to the environment variable
whitelist.
