description:
external/cddl/osnet: Suppress -Werror=stringop-truncation error

This logic correctly uses strncpy(3) to fully initialize a fixed-width field, and also ensures
NUL-termination on the next line as other users of the field expect.

Add -Werror=stringop-truncation to prevent build failure, when run with MKSANITIZER=yes.

Error was reported when build.sh was run with MKSANITIZER=yes flag.
