Log Message:
Update sysutils/rsnapshot to 1.4.3

VERSION 1.4.3
- Restore rsync error code 23 as an important warning.
- Non-LVM backup source breaks after LVM backup source.

VERSION 1.4.2
- Fix double 8 bit shift regression in #65.

VERSION 1.4.1
- Properly capture rsyncs exitcode.

VERSION 1.4.0
- Fix --rsh command line option
  The --rsh option of rsync got errornously quoted (Debian Bug #743310)
- Define traps to unmount LVM parts after fail
  If you use LVM snapshots and rsnapshot fails, rsnapshot will unmount and
  remove the snapshot, too.
- Bail on failing cmd_(pre|post)exec
  If one of those commands fails, rsnapshot will exit with exit code != 0
- Capture output from rsync and print/log if level is >=4
- rsnapshot-diff: Fixed removed files reported as addition (+ mark)
- Introduction of backup_exec resource for running unix commands interspersed
  with backup and backup_script jobs.
- check for SIGPIPE, mainly in case cron fails when trying to mail
  (this is probably why rsnapshot dies mysteriously if it outputs when
  called by cron on a system which does not have mail working).
- When snapshot_root does not exist, check existence of parent directories.
- include_conf `command` now strips backticks before execution (bug fix
  based on suggestion from David Osborn).
- Ignore extraneous output from lvremove command.  (patch by Tim Connors)
- Allow linux_lvm_cmd_* in config file to have options also.
- Allow `backticks with options` in include_conf.
- rsnapshot-diff: Add -s option to show size of each file.
