[scarthgap][PATCH 2/2] oeqa/selftest/devtool: cover update-recipe --initial-rev

[Babanpreet Singh <bbnpreetsingh@gmail.com>]

The --initial-rev option had no selftest coverage. Extend
test_devtool_update_recipe to run update-recipe with --initial-rev
set to the recorded initial revision, which should match the default
output, and to a revision partway through the local commits, which
should export only the commits after it.

(cherry picked from commit 171af3b2915dd076c8d1b205ff75eac1ebd5a586)
[Adjusted for scarthgap: also takes the cleanup_cmd change to this test
from de635a9bc0 ("mdadm: fetch from git"), which the new steps rely on]
