spa: utils: cleanup: fix __has_attribute() usage

Browse source 
Unknown preprocessor symbols are replaced with 0 in preprocessor
conditionals, so if `__has_attribute()` is not supported, then
the condition will be the following:

  if 0 && 0(__cleanup__)

which is syntactically incorrect.

So split the condition and only check `__has_attribute()` if
it exists.

Fixes: 65d949558b ("spa: utils: add scope based resource cleanup")
Fixes #4962
