Tim-Philipp Müller 3f184c3abc tests: include config.h and don't include unix headers
In many cases the unistd.h includes weren't actually needed.

Don't build tests that need it on windows with MSVC
(multifdsink, multisocketsink, pipelines/tcp).

Preparation for making tests work on Windows with MSVC.
