Move the `kernelVerStr()` function duplicated in many
distro definitions to the `rpmmd` package as
`GetVerStrFromPackageSpecListPanic()`.
I could not come up with a better name, sorry.
This will prevent creating another copy of the code in rhel-84 for
the `gce` image.
This change initially exposed a bug in the original implementation of
`kernelVerStr()`. Since on the first line, we allocate an empty structure
into `kernelPkg` variable, it can never be `nil` and the function never
panicked even if there was no `kernel` package in the PackageSpec list.
Fix all unit tests to provide valid arguments when calling `Manifest()`
method of image types.
