modules: add default loader hook implementations

Browse source 
The module loader code allows architectures to hook into the code by
providing a small number of entry points that each arch must implement.
This patch provides __weakly linked generic implementations of these
entry points for architectures that don't need to do anything special.

* module loader code. Architectures that don't need to do anything special
* can just rely on the 'weak' default hooks defined in kernel/module.c.
* Note, however, that at least one of apply_relocate or apply_relocate_add
