Fix checksum for old version of SendJobHeader

[wddgit]

Add back the old checksum which was mistakenly deleted recently
when a new checksum was added and the version changed for the
SendJobHeader class used in the streamer format. Note that no one
reported this problem and probably never would have noticed it because
streamers are normally written and read with the same release.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_3_X IBs unless changes (tests are also fine). @nclopezo, @ktf can you please take care of it?
