TBR: Ignore errors from "make distclean" in snappy.

If snappy has never been built before, the Makefile does not exist, and
running "make distclean" errors with:
    make: *** No rule to make target `distclean'. Stop.

We correctly ignore this error, but it ends up getting printed to the
console, which can be confusing.  This CL discards the output from "make
distclean".
