Let JK_SHM_STR_SIZ be the full byte size including
terminating 0 byte.

Keep copying and comparing JK_SHM_STR_SIZ bytes.
This is now one more byte, but we assume string
length to be at most JK_SHM_STR_SIZ-1 and we
don't want unexpected string truncation to happen.

Still need to add length checks for the configuration
input parameters.
