patchelf: replace a rejected patch with an equivalent uninative.bbclass tweak

This was the original reason to add the patch:
https://git.openembedded.org/openembedded-core/commit/?id=18efcbcb896239c64fedd009ce57f3f0c668cbc0

and this is the upstream discussion which suggests handling
read-only files explicitly outside of patchelf:
https://github.com/NixOS/patchelf/pull/89
