add support for check_readelf_rpath easyconfig parameter to optionally skip RPATH checks

[pavelToman]

This commit adds a new easyconfig variable named 'check_readelf_rpath'. When set to False, RPATH checks by readelf are skipped even if the --rpath flag is present. This provides more flexible control over RPATH validation in specialized build scenarios (as git-lfs).

@pavelToman Can you look into adding a test for this?

Probably test/framework/toy_build.py is a good place.

You can run a particular test using a command like:

python -m test.framework.toy_build  test_toy_rpath

@pavelToman Can you look into resolving the conflict?

Another use case for this is QuPath-0.5.0-GCCcore-12.3.0-Java-17.eb, which also fails in RPATH sanity check (for no good reason).

For now, people can use eb --disable-rpath to dance around it

Checks are failing on:

easybuild.tools.build_log.EasyBuildError: "Installation of toy-app-0.0.eb failed: 'Sanity check failed: Library libtoy.so not found for /tmp/eb-demet2nb/eb-30flw7j2/eb-hftmdbi_/tmpx81fy1mn/software/toy-app/0.0/bin/toy-app'"

For me this PR works either the toy_build.py test - when I run python -m test.framework.toy_build test_toy_rpath it passes OK
