Bug 26852: subfield $e missing in X11 definition of MARC21 headings

Bug 26852: subfield $e missing in X11 definition of MARC21 headings

This patch adds $e to 111 and 611, but removes it from 100 and 110 as it's
used for the relator term there and should not be copied. Same for 111$j.

Test plan:

1. Have a biblio record with, for example, 711 field with a $e subfield.
2. Have two auth records: one with 111 field reflecting the 711 field and second similar but without $e subfield
3. Have LinkerModule set to Default
4. Run link_bibs_to_authorities.pl
5. 711 should remain unlinked since there were two record found by the Default Linker and no one was chosen.

6. Apply the patch.
7. Run link_bibs_to_authorities.pl
8. 711 should be linked now.

Repeat testing in similar fashion for authorities:

9. 100/110 $e
10. 111 $j

NB zebra index definition is OK:
kohaidx:index_match_heading tag="111" subfields="acdefghjklnpqstvxyz" subdivisions="vxyz">
in etc/zebradb/marc_defs/marc21/authorities/authority-koha-indexdefs.xml
