templates: Properly handle multiple initrd paths in 30_os-prober

os-prober now effectively handles multiple paths passed to initrd, but
grub-mkconfig still truncates off any subsequent space-delimited paths.

Support proper parsing of space-delimited initrd paths passed from
os-prober for distributions, like Manjaro, that require it.
