Fix spurious %transfiletriggerpostun execution (RhBug:2023311) 

If a package has multiple %transfiletriggerpostun triggers, any one
of them matching would cause all of them to run, due to disconnect
in the intel gathering stage: we'd gather all the headers with matching
files into a lump, and then add any postun triggers found in them,
but this loses the triggering file information and causes all postuns
to run.

The triggers need to be added while looping over the file matches,
like runFileTriggers() does. Doing so actually simplifies the code.
These should really be unified to use the same code, but leaving
that exercise to another rainy day.
