nissa/nereid: reduce THREAD_MAX_NAME_LEN
The default value for this is 32 bytes, but none of our threads have names
longer than 11 characters. Reducing this to 12 saves 20 bytes per thread,
for total savings of 336 bytes (slightly less than 20 bytes per thread,
presumably due to struct alignment).
BUG=b:223044986
TEST=build & flash nereid, memory reduced and `kernel threads` still shows
full thread names.
BRANCH=none
