remove unused files from HLTrigger area

[mmusich]

PR description:

Issue #46113, which discussed the deprecation of the imp package from python 3.12, made us realize that some of the files that still import it, are in fact unused and substantially unsupported from at least LS2.

HLTrigger/Configuration/test/add/tracingImport.py:import sys, imp,
HLTrigger/Tools/python/PDRates.py:import sys, imp

this PR proposes to just remove them, thus solving the deprecation problem.

PR validation:

None.
