merge revision(s) 345db8f2aa373a31c619c8f85bd372f0a20829c1: [Backport #10902]

	Avoid pointless attempts to open .so file if already required

	When attempting to require a file without an extension that has
	already been required or provided with an .so extension, only
	look for files with an .rb extension. There is no point in
	trying to find files with an .so extension, since we already
	know one has been loaded.

	Previously, attempting to require such a file scanned the load
	path twice, once for .rb and once for .so.  Now it only scans
	once for .rb.  The scan once for .rb cannot be avoided, since
	the .rb file would take precedence and should be loaded if it
	exists.

	Fixes [Bug #10902]
