STDERR tests may fail because of Locale::* deprecation

[eserte]

Here's another module which is the "victim" of the Locale::Country deprecation as a core module in perl. Test log starts with:

#   Failed test 'validate SPARQL'
#   at t/bin.t line 23.
# STDERR is:
# Locale::Country will be removed from the Perl core distribution in the next major release. Please install it from CPAN. It is being used at /home/cpansand/.cpan/build/2018111706/HTML-HTML5-Sanity-0.105-2/blib/lib/HTML/HTML5/Sanity.pm, line 23.
# Locale::Codes will be removed from the Perl core distribution in the next major release. Please install it from CPAN. It is being used at /opt/perl-5.28.0/lib/5.28.0/Locale/Country.pm, line 22.
# invalid SPARQL query
