Find archiso initcpio hooks by path rather than hardcoded location

Current archiso package version may place hooks at a non-standard path.
Use find to locate hooks/archiso and install/archiso anywhere under /usr
and copy to the canonical initcpio location in airootfs.
Prints found paths so build output shows where they came from.
