Clarify that version parameters are not package version strings
Currently linux-version(1) is explicit that the version parameters are kernel version strings and not package version strings. The other manual pages and help texts are not quite as explicit.
Bastian suggested using the term 'release', which would be consistent
with what 'uname -r
' calls this string but not with common usage.
Instead:
- Rename the
VERSION{,1,2}
metavariables toKERNEL-VER{,-1,-2}
- Add 'not the package version' to the descriptions of these parameters
