Add support for RHEL 7.x

[closertotheheart]

I know the CentOS/RHEL support isn't official yet, but what is in the repo is RHEL8 based.

Would be great to have a working RHEL 7.x (7.7 or later) Dockerfile and entrypoint.sh as well (we use Ubuntu 20.04, RHEL 7.7 and RHEL 8.4 at present).

I'd be happy to test it on RHEL 7.x if that's an issue for the dev team prior to merge into master.

Really need this.

I try to build the image by myself. Here is my Dockerfile

ARG D_BASE_IMAGE=docker.io/library/centos:7.9.2009

But even if build very success, and the kernel-dev install properly, but the error still there:
