package/win32: build.sh: add an option to set the PDB source file mapping

This can be useful when cross-compiling. The UNIX pathes need to be mapped
to a Windows path that the debugger can use.

So if you build with "-D c:/vlc" the debugger will look for VLC sources in
c:\vlc, as if they were originally built from there.
