Build tinyipa on focal

Use new ubuntu-focal nodeset to build tinyipa images.
This is needed to prepare to build tinyipa images based on
tinycore 11.x because we need the new kernel 5.x version to
be able to chroot.

Main changes:
- patching tce-load to conform to new squashfs options in the new
kernel
- installing python3-pip instead of python-pip
