disable consoleconf during UC20 install mode

[Dimitri John Ledkov]

[Impact]

 * UC20 displays consoleconf during installation. But it should not be shown. This is because the device is booted into ephemeral mode, and will be rebooted loosing any consoleconf configuration.

[Test Case]

 * Build new core20 snap with new consoleconf package
 * Build new uc20 image with said core20 snap
 * Boot it, and observe that no consoleconf is shown during install
 * Observe that after reboot, consoleconf is shown.

[Regression Potential]

 * Small change to the consoleconf wrapper script, which is only used on core systems / gettys, and otherwise is coded safely (traps any errors and restarts).

[Other Info]

 * This change is merged into subiquity master & uploaded to groovy.
