misc/cgo/testcarchive: split main.c into unix and non-unix

Browse source 
This is in support of https://golang.org/cl/18057 which adds
support for c-archive to the Windows platform.

The signal handling tests do not compile on Windows. This splits
them out into a separate main_unix.c file, and conditionally
includes them for non-Windows platforms.
