Subject: [PATCH] travis: Run "gem install" without sudo

Running "sudo gem install" was causing random errors like the following:

ERROR:  While executing gem ... (Errno::EACCES)
    Permission denied @ rb_sysopen - /home/travis/.rvm/gems/ruby-2.4.1/cache/asciidoctor-1.5.6.2.gem

Perhaps sudo is no longer necessary, even on OS X?  :-)
