[LU-17029] add support for openEuler derived OSes

• Type: Improvement
• Resolution: Fixed
• Priority: Minor
• Severity: 3
• Assignee: Xinliang Liu
• Reporter: Xinliang Liu

Description

Current lustre.spec.in only matchs vendor for openEuler Linux.

But the openEuler derived OSes have a different vendor name, e.g.  KylinOS's vendor name is Kylin.

We should match rpm macro 'openEuler' in the spec for openEuler and its derived OSes a.k.a openEuler family OSes.
