t0210,t0211: unset SANITIZE_LEAK

Turn off TEST_PASSES_SANITIZE_LEAK in t0210 and t0211 tests.

The tests added in a previous commit to confirm that we redact URLs in
the Trace2 output uncovered leaks in `builtin/clone.c` and `remote.c`.

We observed that (1) `the_repository->remote_status` is not released
properly.

And (2) that we are using `url...insteadOf` and that runs into a code
path where an allocated URL is replaced with another URL.

And (3) `remote_states` contains plenty of `struct remote`s whose
refspecs seem to be usually allocated by never released.

More investigation is needed here to identify the exact cause and
proper fixes these leaks / bugs.
