tests: split out manifest case from test-strip-cross.t

The manifest case was added on after the other cases, in d67cfe0d4714
(test-strip-cross: test handling of linkrev crosses in the manifest,
2008-01-20). I think it's easier to read and modify if it's separated.

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