Update to OpenSSL 1.1.1d for Ruby 2.5+

Closes #1232

Set default MAKE=gmake on FreeBSD again

as an workaround for Ruby bug 16331: https://bugs.ruby-lang.org/issues/16331

Due to this bug, build will fail with FreeBSD's make after #1368.
The bug is already fixed in MRI upstream but GNU make is still required
when building older releases of Ruby. Use GNU make rather than switching
make/gmake depending of Ruby version.

Add TruffleRuby 19.3.0

Add definition for mruby 2.1.0

Use the full path to the post-install hook to help debugging issues

• See oracle/truffleruby#1818

Use openssl from Homebrew for TruffleRuby on macOS

• The openssl built by ruby-build was not used by TruffleRuby,
  and causes oracle/truffleruby#1818
• Improve error message when openssl from Homebrew is not available.
• Change the definition code so it checks the operating system too.
