report: adjust lv_active_remotely for shared VGs

Browse Source 
Add a note to the manpage that lvmlockd is unable to determine
accurately and without side-effects whether a LV is remotely active.
Also change the value of the lv_active_remotely option from false to
undefined for shared VGs to distinctly communicate that inability to
users. Only for local VGs it can be definitely stated that they are not
remotely active.
