devtools: Always use unabbreviated commit IDs in github-merge.py
devtools: Always use unabbreviated commit IDs in github-merge.py

Always put the unabbreviated commit IDs in the generated commit messages
and other places. This prevents the developer's `core.abbrev` git setting
from leaking through and is better against ambiguity too.
