cp -a (EXTRACT_CMDS for .sh files) fails inside (non-suid) container if source file has ACL's

[akesandgren]

When running a install of intel-2022a.eb inside a non-suid apptainer container the "cp -a" used to "extract" l_dpcpp-cpp-compiler_p_2022.1.0.137_offline.sh fails if it has ACLs. This is not apptainers fault but rather an effect of the kernel.

So we should change that to use the same actions that the solution for #3910 uses to avoid xattr problems.

Or at least change it to cp -dR

Using cp -a for 'extracting' a .sh was added in #3545.

I consider this fairly important, @boegel thoughts?

fixed in #4465
