lfs: add the '{oid}' template keyword to '{lfs_files}'

The 'sha256:' prefix is skipped because this seems like the most convenient way
to consume it.  Maybe we should also add a '{oid_type}' keyword?  Then again,
that can be added in the future if a different algorithm is supported.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
