[PATCH 3/4] t5541: add test for rejecting a push due to packfile size

["Carlos Martín Nieto" <cmn@dwim.me>]

This rejection requires us to make sure we handle this kind of error
correctly rather than throw away the report in remote-curl and end up
with "Everything up-to-date" due to the lack of report.
