xx-info: handle rhel arch

[crazy-max]

Handle RHEL based distrib for xx-info. This is partially needed for docker/buildx#840 to handle RPM arch package properly. Following distribs are currently handled:

I wonder if we should not take into account ID_LIKE to properly handle RHEL based distrib. Same could be done for Debian based in #49.

In a follow-up we could start thinking about xx-yum.

Remove this line in a follow-up when windres is hanlded for rhel:

I added a check for this in https://github.com/tonistiigi/xx/pull/49/files#diff-97b6828de99e6a75768dba426569ce1a89f0e32542b0ea9c7a3349f47a99263bR16 . Does centos really ship with very old llvm or why isn't this installed?

Does centos really ship with very old llvm or why isn't this installed?

I have not yet updated the test_helper.bash to include yum/dnf. I can add the add/del implementation so the test would pass but we might also need to add xx-yum or xx-dnf.

Also centos and rhel don't have the bats pkg available in their main repo so I might need to fix sources for the test-base-rhel target in the Dockerfile.
