dump: add back kccgst names

Readd the component names to the keymap->names struct. This is used when
printing the component, e.g.

xkb_keymap {
	xkb_keycodes "evdev+aliases(qwerty)" {

instead of

xkb_keymap {
	xkb_keycodes {

This makes diffing against xkbcomp $DISPLAY a bit easier and is kind of
useful anyway.
