[bug#39120] [PATCH 09/12] gnu: ruby-tzinfo: Skip safe tests.

[Christopher Baines]

The safe tests attempt to run with Ruby 2.6, but these tests fail if the build
takes place within /tmp, as the Ruby LOAD_PATH then includes /tmp, which is
world writable.

* gnu/packages/ruby.scm (ruby-tzinfo)[arguments]: Add skip-safe-tests phase.
