[CrashReproducer] Pass -I, -F and -resource-dir to the reproducer script when using modules/vfs 

The reproducer should use -I/-F/-resource-dir in the same way as the
original command. The VFS already collects the right headers but without
these flags the reproducer will fail to do the right thing.
