Eventhough NO_UNIX_SOCKETS was specifically added to support Windows,
it might not be necessary in the future, because Windows added support
for Unix Sockets in late 2017.

The implementation of Unix Sockets, uses an internal NTFS mechanism
and is therefore not visible at the filesystem layer, like it is in
UNIX, but seems to be good enough to allow to build and run the
`git credential-cache` and its daemon, with not many changes.

Additional testing to confirm trace2 (which builds and doesn't fail any
tests) is functional will be also needed.

Interestingly, Cygwin has its own implementation of Unix Sockets that
are visible as such even in the Git Bash environment, but that are also
incompatible with the native ones.

V3 Changes the commit messages as suggested and fixes the original ugly
implementation of the workarounds for the first patch and shoule apply
cleanly as a reroll of cb/unix-sockets-with-windows.
