Updates vmware-fusion6 checksum

The current checksum is not correct for some reason. I removed the .dmg managed
by homebrew-versions and ran `install --force` only to get another checksum
mismatch. I then downloaded the file directly from vmware.com and got the same
checksum that homebrew-version was getting but failing to match.
