Revert r37439 and r37441

r37439:
	* lib/rexml/xmldecl.rb (REXML::XMLDecl): Stop using REXML::Encoding
	  module because XMLDecl doesn't convert encoding. This causes
	  removing XML encoding name normalization (encoding.upcase).
	  Encoding name in XML declaration is what user specifies.
	  I think this is reasonable change.
	* test/rexml/test_xml_declaration.rb: Add tests for the above change.

r37441:
	* test/rexml/test_core.rb (Tester#test_ticket_88): Follow the
	  change that encoding name in XML declaration isn't normalized.
