Package mysql-server-5.6 should Depend: bsdutils for /usr/bin/logger in .postinst

[TJ]

A user reported, for 15.04 Vivid (which appears to continue to affect all releases to 16.04), on a "minimal installation" a failure of the -server post-install script. This appears to be due to a missing dependency on 'bsdutils' which contains '/usr/bin/logger'

debian/mysql-server-5.6.postinst contains the following fragment which is used on the right side of pipes:

# This command can be used as pipe to syslog. With "-s" it also logs to stderr.
ERR_LOGGER="logger -p daemon.err -t mysqld_safe -i"

The installation error was:

invoke-rc.d: Unit mysql.service is masked
/var/lib/dpkg/info/mysql-server-5.6.postinst: line 132: logger: command not found

  * New upstream release.
  * Fix GNU/Hurd build regression (Closes: #793358). Thanks to Samuel
    Thibault.
    - Do not remove .pc in dh_auto_clean as this is wrong. Revert
      previous commit eb6e6d4 that added this.

  * wrap-and-sort
  * d/mysql-server-core-5.6.install: remove duplicate entries. Thanks to Otto
