whonix_createvm: Code simplification.
No longer required to have less ram assigned to the VMs before exporting because Whonix gets no longer build while using Virtual Box inside Virtual Box.
echo
echo
whonixcheck: echo. Removed "clock is set to ...", because it was misleading and could be outdated the moment the user reads it on the gateway.
whonixcheck: removed gpg successfully verified echo. Not interesting for the user and safe some display space on the gateway.
whonixcheck: Changed message for last run of timesync to "Last run (on "$SUCCESS_TIME") of Network Time Synchronization (timesync) successful.",
so the time does not get an ugly line break on the Gateway.
whonixcheck: removed gpg output from echo because it's not useful for users and safes display space on the Gateway.
