Subject: [PATCH] Basic: Adjust condition for include after macro removal in
 upstream LLVM

`HAVE_SYS_RESOURCE_H` was removed in
https://github.com/llvm/llvm-project/pull/123288, so this header is no
longer included at this particular location on rebranch, which breaks
the Linux build, where it is not transitively included either.

Use the same condition as in the use site
(`getChildrenMaxResidentSetSize`) instead.

Also, don't wrap `HAVE_GETRUSAGE` in `defined()` in case it does get
defined to 0.
