Add support for .note.dlopen to add_binary
systemd created a new ELF section to specify `dlopen()` dependencies. See https://github.com/systemd/systemd/commits/main/docs/ELF_DLOPEN_METADATA.md and https://github.com/systemd/systemd/pull/32234.
We should add support for parsing `.note.dlopen` to mkinitcpio's `add_binary` function.
