gprofng: 30602 [2.41] gprofng test hangs on i686-linux-gnu

There were several problems in the gprofng testing:
 - we did not catch a timeout for each test.
 - we used exit() to stop a failed test. But this stops all other tests.
 - we used a time_t (long) type in smalltest.c instead of a long long type.

	PR gprofng/30602
	* configure.ac: Launch only native testing.
	* configure: Rebuild.
	* testsuite/config/default.exp: Set TEST_TIMEOUT.
	* testsuite/gprofng.display/setpath_map.exp: Use return instead of exit.
	* testsuite/gprofng.display/gp-archive.exp: Likewise.
	* testsuite/gprofng.display/gp-collect-app_F.exp: Likewise.
	* testsuite/gprofng.display/display.exp: Delete an unnecessary test
	for native testing.
	* testsuite/lib/display-lib.exp (run_native_host_cmd): Add timeout.
	* testsuite/lib/smalltest.c: Use a long long type instead of time_t.
