[Attributor][FIX] Avoid deleting (internal) library functions

In CGSCC mode we cannot delete internal library functions, esp.
__kmpc_alloc_shared, or we trigger an assertion. While the assertion is
probably too narrow, we avoid deleting those unused functions for now to
unblock the AMDGPU buildbot.
