Ossec-batch-manager.pl exits immediately with error

[seren]

Hi, I believe there's a syntax error in

ossec-hids/contrib/ossec-batch-manager.pl

Line 67 in 226a94a

use Regexp::Common::net;

Currently launching the script produces the error:

Global symbol "%RE" requires explicit package name (did you forget to declare "my %RE"?) at ./ossec-batch-manager.pl line 105.
Global symbol "%RE" requires explicit package name (did you forget to declare "my %RE"?) at ./ossec-batch-manager.pl line 107.
BEGIN not safe after errors--compilation aborted at ./ossec-batch-manager.pl line 139.

Changing the line use Regexp::Common::net; to use Regexp::Common qw(net); eliminates the error.

This import was part of the IPv6 support addition requested discussed in #1276 and implemented in #1667 (commit 999c373)

Given that this change was made 3 years ago and no one has complained, I'm also open to the idea that I'm doing something completely wrong on my end. ossec-batch-manager.pl has been working for us up until we upgraded to the latest version though.

I've opened a PR with the fix, in case it does prove to be the correct solution: #1913

Thanks.
