Bluetooth autotests: do _not_ request permissions to use BT

When running in "ci" test environment, only check them. Normally,
requesting a permission may trigger a system (such as macOS) to
show a popup/alert, requesting a permission to use Bluetooth. But
on CI there is nobody to click 'Allow' button. Even worse
though, the 'trick' with a nested loop was quite useless there, test
was essentially timing out after 15m instead of interrupting the loop
after 30 seconds. Now the part requesting permission is conditional with
testing QTEST_ENVIRONMENT env. variable (which contains "ci"
when running on CI.
