test: add coverage for systemctl preset in test-systemctl-enable.sh

Repeats the enable/disable specifier-expansion check with 'systemctl
preset' instead. preset-all is intentionally not exercised here, since
$root accumulates unit files from earlier sections that are
deliberately invalid, and preset-all would trip on those unrelated
units.
