syscalls: Adjust for lack of 'libutil.so' on glibc >= 2.34.
This is a re-implementation of 3c8b6fd94ceb1e898216929e8768fb518dbf1de9
done in a way that works for both glibc >= 2.34 and earlier versions.
* guix/build/syscalls.scm (syscall->procedure): When LIBRARY is true,
fall back to global symbols if (dynamic-link library) fails.
(cherry picked from commit 3f6c32a88fc7a4d707ae1ed8ef3f7bd995461aff)
