libcommon: eliminate common_vty.c
Move bsc_vty_go_parent() to osmo_bsc_main.c, and greatly simplify. Since
I24cbb3f6de111f2d31110c3c484c066f1153aac9 ("VTY: implicit node exit by
de-indenting, not parent lookup") in libosmocore, the go_parent_cb no longer
needs to provide the proper transition to the parent. The VTY API now actually
remembers which is the current node's parent, as well as what its index pointer
was (i.e. no need to recover the index pointer by a switch on the node id
anymore). The only code worth keeping in the go_parent_cb is the talloc_free()
to free the OML_NODE and OM2K_NODE context when leaving it.
In bsc_nat.c, provide an essentially empty go_parent_cb: after abovementioned
commit, there still needs to be *some* go_parent_cb defined for the generic
node exit to work, even if it doesn't do anything (might be fixed later).
