[Fix] Allow fuzzy worker to listen on AF_UNIX sockets successfully

They can be very tiny (hence the adjustment of the size assert)
and the path can contain intermittent null bytes, so the only choice
is to trust the input slen and copy the whole struct.

An autobound unix socket uses an abstract address, which starts with a
null byte, hence this change is neccesary for such an address getting
copied properly.

Fixes #4278

The source will always be localhost, it makes no sense to check for
allowed IPs.

This reverts commit 5bae837e5f.
