improve ruby-2.5 compatibility (epel8)

Browse Source 
An unfortunate bug in rdoc-5.0 causes a build failure on epel8.  This is
fixed in ruby-2.6/rdoc-6.0.2¹.  Until/unless the fix is backported to
RHEL-8 (which seems unlikely), we can only patch around this.

Thanks, as usual, to Dan Allen for going above and beyond to patch this
upstream.
