x86-64: Add endbr64 to tst-quadmod[12].S 

Add endbr64 to tst-quadmod1.S and tst-quadmod2.S so that func and foo
can be called indirectly.

Reviewed-by: Carlos O'Donell <carlos@redhat.com>

	* sysdeps/x86_64/tst-quadmod1.S (func): Add endbr64 if IBT is
	enabled.
	(foo): Likewise.
	* sysdeps/x86_64/tst-quadmod2.S (func) : Likewise.
	(foo): Likewise.
