[test] [support] Use socket()+bind() to create unix sockets portably

Browse Source 
Replace the mknod() call with socket() + bind() for creating unix
sockets.  The mknod() method is not portable and does not work
on NetBSD while binding the socket should work on all systems supporting
unix sockets.
