Augustin Cavalier 5e9fd9f60d libroot_build & fs_shell: Provide _kern_ functions for readv/writev...
..instead of readv_pos/writev_pos. This way, we can be sure that we
are remapping them properly even under Haiku, as well as remove some
potential confusions.

bfs_shell seems to still work fine on a regular build.
