jobsub: add run number to suffix in addition to hash

Before:

jobsub_dsipm_timeana_0ca06b3a3efbd7e76da4b98e7255619c.conf

While the hash is nice to hide all the parameter given, if you have many runs there is a) no sorting, and b) it's not as trivial as it should be to figure out which run actually belongs to a certain log file since neither jobsub nor corry doesn't log it with a high log level.

After:

jobsub_dsipm_timeana_5545_0ca06b3a3efbd7e76da4b98e7255619c.conf

Much better an still short enough.
