build-qemu-robot-docker: update to jammy

The HEAD of the OpenBMC now builds the QEMU binary with GLIbc_2.33. But
this QEMU-Robot-docker still uses GLIbc_2.31, which causes
run-qemu-robot to fail.

The fix is to simply update the base image to jammy which has a newer
version of glibc.

This commit also fixed imcompatible packages in the build script:
python2.

Tested: run-robot-test-qemu worked on the Romulus image built from HEAD
