Set NODELETE flag when opening already open objects with RTLD_NODELETE
The DF_1_NODELETE flag is set too late when opening a DSO, due to
which, if a DSO is already open, subsequently opening it with
RTLD_NODELETE fails to set the DF_1_NODELETE flag.  This patch fixes
this by setting the flag immediately after bumping the opencount.

Verified on x86_64.

	[BZ #18676]
	* elf/tst-nodelete-opened.c: New test case.
	* elf/tst-nodelete-opened-lib.c: New test case module.
	* elf/Makefile (tests, modules-names): Use them.
	* elf/dl-open.c (dl_open_worker): Set DF_1_NODELETE flag
	early.
