Sign-extend start and stop address inputs to objdump

[Alan Modra]

git commit 2379f9c475 introduced an rx-elf test failure.  This fixes it.

	* testsuite/binutils-all/objdump.exp (test_objdump_disas_limited),
	(test_objdump_content_limited): Add text arg, use in place of .text.
	(bintest_signed.o): Call get_standard_section_names for name of
	text section.
