cpictl: Handle excessive kernel version numbers

Browse Source 
Some development kernel versions provide an 8-digit date number like
"20220325" in place of the second kernel sublevel, while the data
format used to send this information to the HMC only supports 16 Bit
numbers. As a result, the HMC displays a seemingly random sublevel
number.

Fix this by replacing excessive sublevel numbers with 0 to ensure that
these numbers are handled consistently.
