testAllBlockDevicesAreSecure: move to host side test

The testAllBlockDevicesAreSecure test is broken. Having
testAllBlockDevicesAreSecure as a device side test would require
granting permissions to the untrusted_app domain, which was
undesirable.

Move this test to host side and add permissions for shell to getattr
on block devices.
