testsuite: analyzer: drop stderr from deref-before-check-2.c

On some VxWorks targets, stderr is #defined to a function call, and
this confuses the analyzer in test_1, so we skip the warning.  That
appears to reveal a bug in the analyzer, but it doesn't seem to be
what the test was meant to test, so I'm dropping this unintended
feature from this testcase and filing PR124672 with a testcase to
reproduce it elsewhere.

	* c-c++-common/analyzer/deref-before-check-2.c (test_1):
	Drop stderr.
