Get rid of patchelf requirement

OpenSSL has the configuration option shlib_variant, so we can use that instead.

This works for version 1.x and 3.x, so it would make the build script more similar between the two versions.

Also, this avoid issues that can come from patchelf, as this patch comes after a bug found in patchelf 0.18 that created wrongly aligned libraries. See https://github.com/NixOS/patchelf/issues/492.
