Detect test cases that require something not to be supported

Browse source 
PSA_xxx_CATEGORY_yyy is used in metadata tests where it doesn't
involve any particular support, and elsewhere it's used as a value
that is definitely not supported but is in a plausible range. Such
symbols do not require any dependency.

If a test case is expects PSA_ERROR_NOT_SUPPORTED, its
dependencies (often including one negative dependency) cannot be
determined automatically, so leave that test case alone.
