Subject: [PATCH] core: reinstate propagation of stop/restart jobs via
RequsiteOf dependencies
This reverts the primary effect of be7d9ff730cb88d7c6a869dd5c47754c78ceaef2.
After all Requisite= should be close to Requires=, without the one
exception that it doesn't pull in dependencies on start. However,
reverse deps on stop/restart should be treated the same way as for
Restart=, and this is already documented in the man page, hence stick to
it.

(cherry picked from commit ce74e76920dca603a12ef4bf605567965e9e7e45)
[msekleta: we didn't backport be7d9ff730cb88d7c6a869dd5c47754c78ceaef2
and hence we don't have UNIT_REQUISITE_OF. Note that this patch was
backported because it makes backports of followup patches easier]
