[DRE-maint] Bug#836206: lolcat: shebang should not use env

[Kazuhiro NISHIYAMA]

Package: lolcat
Version: 42.0.99-1
Severity: normal

Dear Maintainer,

I use rbenv and install ruby to PATH before /usr/bin.
So "#!/usr/bin/env ruby" runs with ruby which does not have dependent packages (ruby-paint, ruby-trollop).

Actual result:
% lolcat /dev/null
/path/to/rbenv/versions/git/lib/ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- lolcat/version (LoadError)
        from /path/to/rbenv/versions/git/lib/ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require'
        from /usr/games/lolcat:21:in `<main>'
%

Expected result:
% /usr/bin/ruby $(which lolcat) /dev/null
%
