Missing murmurhash.c

[fvieira]

In commit 1515b91, superfasthash was replaced with murmurhash3.
You removed superfasthash.h and superfasthash.c, and added murmurhash3.h, but it seems to me that you forgot to add murmurhash3.c...

Thanks, good catch! I didn't noticed this before because local tests were passing (murmurhash.c was not in VCS, but it was in a proper place locally so it gets included to sdist).
