21.6 Rivet_i: skip weight-name cleaning for unnamed weights

Special handling for evgen MP

See merge request atlas/athena!32295

In evgen we need to handle MP a bit differently. This is my attempt,
which seems to avoid errors in the transform itself. The problem is that
we normally disable MP during the job, so that the output file appears
as just a simple output file with whatever name has been assigned by the
transform. There aren't a bunch of workers. Very happy to have input on
whether there's a better way to do this!

The temporary file to which this line refers is no longer created, so it
doesn't need to be deleted.

It must be an integer. Casting it into one.

This adds one of the central PDF fragments to the common SUSY setup. It
was discussed in the Background Forum meeting on 14.4 and agreed that
this would be done. This brings the SUSY setup in line with the current
PMG recommendations, and has the nice benefit of including systematic
variations in a standard way.

As documented on the MG questions page:

There actually need to be spaces at the beginning of the lines
specifying decays in order for them to be correctly interpreted by
MadSpin. I didn't see this coming, that's for sure. This fixing an issue
when applying the Higgs decays.
