nissa: shrink shell TX ring buffer
The EC default of 1k seems unnecessarily huge, especially compared to
the Zephyr default of 8 bytes. Shrinking it to 128 bytes doesn't have
any apparent ill effect, and reclaims a lot of RAM.
BUG=b:223044986
TEST=flash nereid, console output looks normal and RAM usage is reduced
by 896 bytes.
BRANCH=none
