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. Signed-off-by: Longjun Luo <[email protected]>
