Subject: [PATCH 04/10] fs: make filesystems.c explicitly non-modular

The Makefile currently controlling compilation of this code is obj-y
meaning that it currently is not being built as a module by anyone.

Lets remove the traces of modularity that we can so that when reading
the code there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering gets bumped to one level earlier when we
use the more appropriate fs_initcall here.  However we've made similar
changes before without any fallout and none is expected here either.

We can't remove module.h from the file as we've done in similar
cleanups, since other code in the file is using module functions
to try and load filesystem drivers etc.
