modctl: fix install check on aarch64-darwin

modctl creates a ~/.modctl directory before running any cobra command.
Go's os/user package doesn't respect $HOME on darwin and does system calls
directly, so the installCheckPhase fails there.

Pass --log-dir and --storage-dir pointing at $TMPDIR to avoid touching $HOME.
