Device test fails for B2Qt device with missing 'base64' dependency

Steps to reproduce:

1. Install B2Qt content via installer (with QtC 8.0.x version)
2. Try adding a 'Boot2Qt Device' from Edit -> Preferences -> Devices -> Add...

Expected result:

The Device Test passes

Actual result:

The Device Test fails with 'base64' dependency check. 'base64' is not found from Boot2Qt images.

Sending echo to device...
Device replied to echo with expected contents.


Checking kernel version...
Linux 5.4.161-0+git.0f0011824921 armv7l


Checking if specified ports are available...
All specified ports are available.


Checking whether "sftp" works...
"sftp" is functional.


Checking whether "rsync" works...
"rsync" is functional.


Checking if required commands are available...
base64...
base64 not found. 

This means, that trying to use any Boot2Qt image with QtC 8 is not possible. Is the 'base64' dependency mandatory to be checked from B2Qt images? If the dependency was added to B2Qt images, still the older B2Qt versions would not work with QtC 8 or newer since old images do not have 'base64'.
