Support for Oracle Linux 7 and Oracle Linux 8

[viniciusferrao]

There's no support for recent versions of Oracle Linux on xCAT. Only Oracle Linux 6 seems to be supported and this version is extremely old.

We started deploying clusters with Oracle Linux using the PR #6919 as a hotfix on upstream packages. Since everything changed didn't need to be compiled it worked as expected.
