Subject: [PATCH] kpatch-build: add support for OpenCloudOS

OpenCloudOS is a centos-like Linux distribution.
I test kpatch in OpenCloudOS V8 and V9.
It works well in V9. But v8 itself has two problems:
1. no available epol repo, so kpatch can't install ccache.
2. executing 'uname -r' can't get an accurate kernel version.

Both problems have been notified to the OpenCloudOS community.
After they fix these problems, kpatch will work well in all versions.
