Avoid deprecated sigblock in misc/tst-pselect.c.

misc/tst-pselect.c uses the deprecated sigblock interface, resulting
in "tst-pselect.c:42:3: warning: 'sigblock' is deprecated (declared at
../signal/signal.h:189) [-Wdeprecated-declarations]".  The choice of
sigblock rather than sigprocmask has nothing to do with what this test
is testing, so this patch changes it to use sigprocmask to avoid the
warning.

Tested for x86_64.

	* misc/tst-pselect.c (do_test): Use sigprocmask instead of
	sigblock.
