Crmc Compatibility Update, master branch (2021.11.12.)

Made Epos_i and QGSJet_i smarter with installing files from Crmc. This is necessary to find those files in different versions of Crmc.

This is a follow-up to !48181 (merged). It is meant to fix the current CMake configuration issue in the master--dev4LCG nightly.

As a note to the shifter: Discipline around notifying me of MRs with non-trivial CMake changes is pretty lax these days. 😦 I would've loved to be notified of !48181 (merged)...

This is also tied to SPI-2024, and atlasexternals!890 (merged). But it can be merged in independently from the latter.
