Cannot run Gluten on RHEL OS

[weiting-chen]

Describe the bug
This is a customer case who is trying to run Gluten on RedHat Enterprise Linux 7.9 and report below error:
"cannot be cast to io.glutenproject.utils.VeloxSharedlibraryLoader"

To Reproduce
Run binary jar on RedHat OS

Expected behavior
CentOS is downstream of Red Hat Enterprise Linux, the users may expect Gluten can run on CentOS and RHEL can be supported as well.

Additional context
Assume this is a slight effort to support RHEL, because CentOS is downstream of RHEL.
Just to add the os name and version support into below file:
