consider `getent` alternative, doesn't exist on busybox (eg. BalenaOS): Could not find user in /etc/passwd

It breaks the script early eg: x11docker ERROR: Could not find user '...' in /etc/passwd.

Sorry for my late response.
I have replaced getent with a custom function using grep. That should fix this.
However, it is likely that some other commands might miss in busybox, too. Would you mind to update x11docker and try out?

Just curious, x11docker runs well on alpine that in turn is based on busybox. Maybe busybox in alpine provides more tools than busybox in BalenaOS?

I had a look if I could run BalenaOS in Virtualbox, but there was no straightforward way.
