TODO(sprof): cheri: disable profiling shared libraries
This is needed now to avoid referencing abort in ld.so. TODO: Fixing shared library profiling for capabilities requires type fixes so capabilities are not stored into shared memory (maybe purecap layout can match the lp64 one and then no file format and external tooling change is required.) TODO: Proper fix also depends on _dl_runtime_profile plt entry
