ltmain.in: Expand process.h inclusion on Windows

Multiple compilers on Windows besides the proprietary MSVC compiler
require process.h, and not unistd.h. The inclusion check is expanded
to include these alternative compilers which also require process.h.

* ltmain.in: Replace _MSV_VER with WIN32 and !__GNU_C check
