gb: drop special vty exit commands, use vty_install_default()

L_NS_NODE and L_BSSGP_NODE had specialized 'exit' and 'end' vty commands, but
all they do is return to the CONFIG and ENABLE_NODEs like the default 'exit'
and 'end' commands. Drop them and use the default 'exit' and 'end' cmds.

Examining BSSGP and NS node behavior in osmo-sgsn exhibited identical list and
exit/end behavior before and after this patch.

Prepares for an upcoming commit incorporating vty_install_default() into
install_node(), see I5021c64a787b63314e0f2f1cba0b8fc7bff4f09b: this patch
changes to the default commands, the upcoming change implies them.
