[libc-commits] [libc] [libc] Fix scudo integration test (PR #92967)

[Michael Jones via libc-commits]

https://github.com/michaelrj-google created https://github.com/llvm/llvm-project/pull/92967

When scudo is built with LLVM-libc's headers, certain functions also
need to be linked from LLVM-libc. This patch adds those functions to the
list to be linked into the specific scudo test, which uses a minimal
subset of libc.

Fixes #92861 and #59453
