RFR 8231187: SelectorProvider.inheritedChannel() returns TCP socket channel for Unix domain socket

[Michael McMahon]

Hi,

This issue was reported through a recent discussion proposing an API for 
Unix domain
sockets. It fixes the current erroneous behavior where TCP type 
SocketChannels are returned
and instead returns a Channel type which handles connected AF_UNIX 
sockets specifically.

The fix also enables the whole inherited channel mechanism for Mac, 
which up to now
has not been working.
