In the next commit we'll use this same mnemonic to get a listener for the
nth filter, so we need it available outside of CHECKPOINT_RESTORE in the
USER_NOTIFICATION case as well.
v2: new in v2
v3: no changes
v4: no changes
v5: switch to CHECKPOINT_RESTORE || USER_NOTIFICATION to avoid warning when
only CONFIG_SECCOMP_FILTER is enabled.
