Willy Tarreau 22ccd5ebaf BUG/MEDIUM: listener: make the master also keep workers' inherited FDs
In commit 374e9af35 ("MEDIUM: listener: let do_unbind_listener() decide
whether to close or not") it didn't appear necessary to have the master
process keep open the workers' inherited FDs. But this is actually
necessary to handle the reload on "bind fd@foo" situations, otherwise
the FD may be reassigned and the new socket cannot be set up, sometimes
causing "socket operation on non-socket" or other types of errors.

William found that this was the cause for the consistent failures of the
abns regtest, which already used to fail very often before this and was
as such marked as broken.

Interestingly I didn't have this issue with my test configs because
the FD number I used was higher and within the range of other listening
sockets. But this means that one of these wouldn't work as expected.

No backport is needed, this was introduced as part of the listeners
rework in 2.3.
