redhat: Create unique debuginfo packages for kmods

Commit 443dd5367e0cd9050ad39a6594c5be521271b4e9 ("redhat:
separate debuginfo package for kmod rpm") introduced the
creation of separate debuginfo packages for the kmod packages.
As such, this is useful, but all debuginfo packages for a given
OpenAFS release ended up with the same name/version/release for
the kmod debuginfo package, no matter which kernel release or
variant the kmod was built for.

Move the additional black magic from the spec into the kmodtool
script where we have the means to do better: Use the same naming
and versioning conventions as for the kmod-openafs packages
themselves.
