adafruit-pitft.py - Red warnings if /etc/gdm3/custom.conf does not exists.

[riktam]

Running adafruit-pitft.py on Ubuntu 22.04.5 LTS

python3 adafruit-pitft.py --display=35r --rotation=270 --install-type=console

I get the following "red lines":

PITFT grep: /etc/gdm3/custom.conf
PITFT : No such file or directory
PITFT sed: can't read /etc/gdm3/custom.conf: No such file or directory

The script does not stop and seems to finish correctly but it's an error anyway. I my case the /etc/gdm3 did not exist.
