Call _dl_open_check after relocation [BZ #24259]
This is a workaround for [BZ #20839] which doesn't remove the NODELETE
object when _dl_open_check throws an exception.  Move it after relocation
in dl_open_worker to avoid leaving the NODELETE object mapped without
relocation.

	[BZ #24259]
	* elf/dl-open.c (dl_open_worker): Call _dl_open_check after
	relocation.
	* sysdeps/x86/Makefile (tests): Add tst-cet-legacy-5a,
	tst-cet-legacy-5b, tst-cet-legacy-6a and tst-cet-legacy-6b.
	(modules-names): Add tst-cet-legacy-mod-5a, tst-cet-legacy-mod-5b,
	tst-cet-legacy-mod-5c, tst-cet-legacy-mod-6a, tst-cet-legacy-mod-6b
	and tst-cet-legacy-mod-6c.
