build: Add Visual Studio compat headers

Visual Studio does not come with unistd.h and utime.h, so building items
that originate from glib-2.0.vapi et al will fail if items that depend
on these headers are used.

Do overcome this, add compat headers for them that will include the
appropriate headers from Visual Studio (or the Windows SDK), to fix the
build.
