Bug Description

In Ubuntu Bionic's Ping.pm a test of the used socket's version is done numerically although the Socket.pm's version contains a special character ("_") which causes this warning message:

Argument "2.020_03" isn't numeric in numeric ge (>=) at /usr/share/perl/5.26/Net/Ping.pm line 1801, <DATA> line 755.

Since Socket.pm is part of the same package, the test is not really useful anymore. I suggest removing it quick'n dirty via the attached patch to get rid of the warning while conserving the "old way".

Thanks for the patch, I tried it and suggest the following instead (removing the "_" and everything beyond in the Version string) so that it actually keeps its behaviour for versions prior to 1.94 and in addition to that I encountered a third location where $Socket::VERSION is being used inside that file:
