wwan: T7487: only wait for a modem in start_modem_manager()

modem_index() unconditionally polled for up to modem_wait_timeout before
returning None, so every caller that expects "no modem" as a routine
outcome - interface teardown, admin-disconnect markers, disconnect/connect
status checks, and vyos-netlinkd's reconcile loop checking every configured
interface once per pass - blocked on it too. The reconcile loop in
particular calls is_wwan_connected() synchronously, not per-interface, so
one interface with no modem stalled the whole daemon's reconcile pass,
including unrelated DHCP interfaces, every cycle.

Add a wait parameter, default False (single check, returns immediately).
Only start_modem_manager() passes wait=True, where waiting for a
still-initializing modem is the actual point.
