kernel/vfs: minor vfs_request / vfs_root_register rework

* changed vfs_root_register's name because the _mount didn't add anything
* removed the old pointless vfs_backend_tryaccept calls from drivers
* because of that, i could remove the vfs_backend globals
* replaced the horrible BACKEND_KERN macro
* all vfs_backends are now stored on the heap
