Subject: [PATCH 1/4] selftests/nolibc: make evaluation of test conditions
If "cond" is a multi-token statement the behavior of the preprocessor
will lead to the negation "!" to be only applied to the first token.
Although currently no test uses such multi-token conditions but it can
happen at any time.
Put braces around "cond" to ensure the negation works as expected.
