Bug 15012: use sudo instead of su in koha-shell

Bug 15012: use sudo instead of su in koha-shell

Not sure this is the best way to fix it but it looks to work.

Test plan:
  sudo koha-shell kohadev
should not return any error
Without this patch, you should get
  bash: cannot set terminal process group (-1): Inappropriate ioctl for device
  bash: no job control in this shell

Confirm that other options work as before

Works as expected. Tested on kohadevbox:ansible.
KOHA_CONF and PERL5LIB are correctly set on the child shell.
Bonus point: koha-shell doesn't die if the user issues Ctrl+C to abort an execution.
