Permission denied while building BioPerl

[TopRichard]

When trying to build BioPerl, the build process fails with:

== permissions...
== ... (took < 1 sec)
== packaging...
== ... (took < 1 sec)
== FAILED: Installation ended unsuccessfully (build directory: /tmp/bot/easybuild/build/BioPerl/1.7.8/GCCcore-12.2.0): build failed (first 300 chars): Failed to copy file /cvmfs/software.eessi.io/versions/2023.06/software/linux/x86_64/generic/software/EasyBuild/4.9.2/lib/python3.11/site-packages/easybuild/easyblocks/generic/perlmodule.py to /tmp/eb-fftevtnk/eb-ak3d7syr/reprod_20240805124945_346/easyblocks/perlmodule.py: [Errno 13] Permission denie (took 1 min 36 secs)

Work around by using --include-easyblocks-from-commit=latest commit to easyblock repo

I think this is related to https://github.com/easybuilders/easybuild-framework/blob/develop/easybuild/tools/filetools.py#L2404 not having an avenue to check that if the if the source and the target both exist, only bother with the copy if the contents differ

Fix in #4604
