Tell GitHub our test files are Perl 5, not Perl 6

This fixes incorrect reporting by GitHub that our repo's test files are written in Perl 6:

Not sure about this. I feel like this is really GitHub's problem and they should just be doing a better job with detecting languages.

Has this actually been reported to GitHub as a bug yet?

[zoffixznet]

I see two closed tickets 2074 and 2149 that cover the issue.

Since .t can mean both Perl5 or Perl6, Linguist does some heuristics to figure out which language it is, and since the two languages are similar, in this case it's failing.

Adding a perl shebang, adding use strict;, or adding use v5.XXX will fix it, and another solution provided in the answer to why the issue likely won't be fixed is to use .gitattributes file, which is what this PR has done.

I've commented on one of the issues. github-linguist/linguist#2149 (comment)

Clear 👎 from me. This is a problem that needs to be solved in Linguist (not just for us, but for the entire Perl community). Also, the workaround doesn't appear to work for syntax highlighting either.

You know what, the discussion here, on IRC, and reading the Linguist tickets actually changed my mind about this PR as well, since this isn't the first time I'm forced to add .gitattributes (here, here, and here).

I agree popularity of a language should be factored into Linguist's heuristics and we shouldn't mindlessly work around a problem in the tools. The tools need to be fixed.
