ohos: declare the permission dialog blocking the autotests

ACCESS_BLUETOOTH is a user_grant permission, so the first run after an
install stalls on a consent dialog that cannot be suppressed. Match it
on the strings the system generates for it, not on the reason text the
tested app supplies, which differs per application.

Two buttons, because the dialog appears as Deny/Allow and as a list of
choices needing a separate confirmation.
