activate: skip manual activation for --sysinit -aay

Browse Source 
When --sysinit -a ay is used with vg/lvchange and lvmetad is up and running,
we should skip manual activation as that would be a useless step - all volumes
are autoactivated once all the PVs for a VG are present.

If lvmetad is not active at the time of the vgchange --sysinit -a ay
call, the activation proceeds in standard 'manual' way.

This way, we can still have vg/lvchange --sysinit -a ay called
unconditionally in system initialization scripts no matter if lvmetad
is used or not.
