-Fix a test failure on 32-bit platforms as reported

-Subject: [PATCH] tests: don't run buf::oom on 32-bit systems
-
-On a 32-bit Linux systems, the value large enough to make malloc
-guarantee a failure is also large enough that valgrind considers it
-"fishy".  Skip this test on those systems entirely.
