cli-tests/t_v1_policy: clean up user keyrings at end of test

The test user's user keyring is still linked into root's user keyring at
the end of the test.  This is making the test flaky, as there is a
failure that only occurs the first time it is run.  Fix the test to
restore the initial state.  This makes it consistently fail (to be fixed
by the next commit).

 # Gives the test a new session keyring which contains the test user's keyring
 # but not root's keyring.  Also clears the test user's keyring.  This must be
 # called at the beginning of the test script as it may re-execute the script.
