compiler/protogen: allow specifying the package name with M flags

When using the M flags (which is functionally a mapping of
filenames to Go package paths), provide the user the ability to also
specify the package name by delimiting the package path with a ";".

Example usage:
	Mpath/to/foo.proto=path/to/foo_go_proto;foopb

This uses the exact same syntax as the go_package option where a
";" delimiter can be used to specify a package name.
It brings the M flags and the go_package option closer in behavior.
