autotools: tests: disable test_fork if fork() is not available

fork() support is optional and its availability is correctly detected at
contfigure time.

But test_fork was all always built, preventing build for targets that do
not provide fork() from building successfully.

This pacth fixes the autotools on this point.

ipc: fail harder for abstract ipc on non-Linux

Using 'ipc://@abstract-socket' on non-Linux platforms yields inconsistent
behaviour.  Abstract sockets don't exist, so the literal file is created.
The test previously failed, but for a different reason: this is not the
directory you are looking for.  Now, zmq_bind() will fail for the right
reason: the socket can't be created.  Put the XFAIL back.
