With DISABLE_TESTS_CORE_DUMPS, setrlimit(RLIMIT_CORE, 0) only prevents
core dump files from being written, but when systemd-coredump is
configured as a piped handler (via core_pattern), the kernel still
invokes it regardless of RLIMIT_CORE, so entries appear in
coredumpctl. Adding prctl(PR_SET_DUMPABLE, 0) marks the process as
non-dumpable, which prevents the kernel from invoking the core dump
handler entirely — including piped ones.
