compiler/protogen: make paths=import work with M overrides

In the default .pb.go filename generation mode, we generate the filename
from the import path when a file has a go_package option and the source
.proto filename otherwise.

Change filename generation when an explicit mode of paths=import is
specified to always use the import path, no matter how it was
determiend. The practical effect is that you can override the import
path of a file with Mx.proto=import/path and have this behave
identically to setting a go_package option in the file.
