Make IO::Socket::SSL-dependent tests optional

[zoffixznet]

Currently, attempting to install the module fails with the message below. The IO::Socket::SSL-dependent tests need to check for presence of IO::Socket::SSL before using it.

An alternative and worse solution is to list IO::Socket::SSL in the dependencies.

===> Testing: LWP::Simple:ver('0.087'):auth('Cosimo Streppone')
501 Protocol scheme 'https' is only supported if IO::Socket::SSL is installed <URL:https://doc.perl6.org/type.html>

+1 - this breaks the install process.

This is fixed. What was previously a http test url changed to redirect to a https url which I changed to another http test url.

I don't recommend listing IO::Socket::SSL as a required dependency since this opens a can of worms to do with OpenSSL binary libraries on Rakudo Star etc.

I'm still seeing an issue with 4991a1b:
