sysutils/bacula11*: revert 'Remove expired bacula11 ports"

I'm a month early.

This reverts commit ea825e27e6509f78d11e26e13a4bf83aaca17110.

In order to commit this revert, I had to remove distinfo from
net-mgmt/nagios-check_bacula11 because it did not contain a
timestamp - the file is not required because it is a slave
port.
