modula-2: Module registration constructors need to be visible [PR108259].

In the current design the main executable links explicitly to the module
registration construtors that it uses.  This means that they must be
visible in shared libraries.

	PR modula2/108259

gcc/m2/ChangeLog:

	* gm2-gcc/m2decl.cc (m2decl_DeclareModuleCtor): Make module
	registration constructors visible.
