Subject: [PATCH] limine: align concatenated initrd modules to 4 bytes

The kernel's initramfs unpacker only accepts a raw cpio header at a
4-byte aligned offset, so multiple module_path entries need padding
between them. Without this an uncompressed cpio after the main
compressed initrd fails with "invalid magic at start of compressed
archive".

Patch merged upstream as Limine PR #599, remove on next release.
