Remove test_crossdirect_rust, the only test in test_crossdirect.py. The
behavior that was tested here with all the "mv /usr/bin/rustc" commands
was specific to version 4 and isn't valid anymore since version 5
(pmaports MR 4234).
The previous behavior was that crossdirect always tried to run rustc
from /native, and if it failed, it would fall back to using qemu. The
new behavior is that it runs rustc from /native only when it expects it
to succeed, and runs rustc via qemu otherwise, without attempting
/native first. As the logic to decide whether to use native rustc or not
is now done beforehand, it does not do the fallback to qemu if native
fails.
Note that the test hasn't been failing because we switch to the v23.06
channel and therefore use the older crossdirect version.
