dma-buf: heaps: system: Turn the heap into a module

Browse Source 
The system heap can be easily turned into a module by adding the usual
MODULE_* macros, importing the proper namespaces and changing the
Kconfig symbol to a tristate.

This heap won't be able to unload though, since we're missing a lot of
infrastructure to make it safe.
