Perl 5.14 regex syntax breaking older perl version

[gfeun]

Hello,

Version 1.4.0 broke support for perl versions older than 5.14.

A regex flag introduced in Perl 5.14 has been used here

$ perl -v 
This is perl, v5.10.1 (*) built for x86_64-linux 

Bareword found where operator expected at /app/t/../local/lib/perl5/Log/Dispatch/Gelf.pm line 86, near "s/\n.*//sr"

Fix would be to find a 5.10 compatible option or drop support and advertise 5.14+ support in Meta.json and cpanfile.

Thanks !
