This also switches all these notes to be defined via SD_ELF_NOTE_DLOPEN_ANCHORED(). Consequently, any notes added within unreachable or unused functions will be automatically garbage-collected by the linker (--gc-sections) instead of bloating the final binary. E.g. unused p11-kit library dependency is now dropped from systemd-repart.standalone binary.
