piuparts_tap: don't check only for error code 100 but accept any digit

While we usally received status=100 on errors, there might
be different status codes, e.g. when removing packages goes
wrong:

| ERROR: Command failed (status=1): ['chroot', '/var/cache/pbuilder/tmp.Vm9yxXRdcF_piuparts_tmp/tmpLZmcmg', 'eatmydata', 'dpkg', '--purge', '--pending']
