Bug 16720: Remove DBIx ActionLogs.pm

Bug 16720: Remove DBIx ActionLogs.pm

The update_dbix_class_files.pl script generates ActionLog.pm instead, which is
already on the source tree.

To test:
- Apply the patch
=> SUCCESS: Koha/Schema/Result/ActionLogs.pm is removed
- Run:
  $ mysql -uroot
  > CREATE DATABASE dbic; \q
  $ mysql -uroot dbic < kohaclone/installer/data/mysql/kohastructure.sql
  $ misc/devel/update_dbix_class_files.pl --db_name dbic --db_user root
=> SUCCESS: Koha/Schema/Result/ActionLogs.pm is not re-generated
- Run:
  $ git grep ActionLogs
=> SUCCESS: There's no code using it
- Sign off
