supplicant: merge NEW_BSS signal with BSS_UPDATED
Before, the NEW_BSS signal was not careful to emit the signal only when the BSS
is seen for the first time. Consequently, supplicant_iface_new_bss_cb() checked
whether it already knows about the new BSS.
Merge NEW_BSS and BSS_UPDATED. Now we emit BSS_UPDATED when either the
BSS is new or changed.
Also, in supplicant_iface_new_bss_cb() (now supplicant_iface_bss_updated_cb())
no longer constructs an @ap instance if we have a @found_ap.
In some situations there can be a value of having a separate ADD signal.
But only when there the consumers care, and if the consumers can trust that
ADD is not just an UPDATE. The only consumer doesn't care and it not not be
trusted, so merge the signals.
