RootTargetPreparer: add option to ignore failure and carry on with setup

In some scenarios tests (e.g CtsInitTestCases, CtsFsMgrTestCases) are
shared between different test suites (e.g. cts, vts) which means that
some of the tests cases require root, while others don't.

Adding an option to ignore failure of `adb root` will make it possible
to run those tests on both user and userdebug builds via the same
command (e.g. atest CtsInitTestCases).

Test: locally added RootTargetPreparer to CtsInitTestCases
Test: run atest CtsInitTestCases on aosp_blueline-user
Test: run_tradefed_tests.sh
