Bug 35591: Prevent bulkmarcimport from replacing local auth_header

If you run bulkmarcimport,pl on authorities with --update (or --all)
it will overwrite a local auth_header if the auth_id of a local
auth_header matches the control-number (field 001) of an imported MARC
record.

This patch adds a new option --guessauthid (which is still enabled by
default to keep the script backwards compatible, but broken), which can
turn off this behaviour if called as --noguessauthid.

To test with koha-testing-docker:

* Inspect cgi-bin/koha/authorities/detail.pl?authid=1402 which should be
  PERSO_NAME of Aristotles.
* get the file twin_040682714.xml from Bugzilla and make it available
  inside of koha-testing-docker
* run:
  misc/migration_tools/bulkmarcimport.pl -m MARCXML -c utf8 -a --file
twin_040682714.xml --all --match isbn,001
* Check cgi-bin/koha/authorities/detail.pl?authid=1402, which now is a
  TOPIC_TERM "Zwilling" (twin...)

Reset koha-testing-docker, apply the patch

* run with the new flag
  misc/migration_tools/bulkmarcimport.pl -m MARCXML -c utf8 -a --file
twin_040682714.xml --all --match isbn,001 --noguessauthid

* cgi-bin/koha/authorities/detail.pl?authid=1402 still is "Aristotle"

* "Zwilling" is cgi-bin/koha/authorities/detail.pl?authid=1708 (at least
  on my ktd, the actual id might vary)
