Provide custom REs for the dist tag and kernel version

It was decided (citing dubious reasons) to arbitrarily change
the way GA kernel version is versioned, breaking existing assumptions.
Accomodate for that.

* 0002-kernel-version-re-fix.patch: New file.
* ddiskit.spec (Patch0002): New patch.
(%prep): Apply it.

Resolves: RHEL-61716
