Subject: [PATCH] lava: add fastboot_fastrpc template for correct firmware
 archive merge

Introduce templates/boot/fastboot_fastrpc.jinja2 for FastRPC LAVA jobs.

FastRPC jobs provide firmware in archives. Combining kernel firmware and fastrpc
firmware archives with `cat` does not merge filesystem structures and can break
symlink/path resolution during early boot (e.g., /lib -> /usr/lib with firmware
delivered in a separate archive). This leads to firmware load failures.

The new template performs an extract-into-one-dir + repack workflow to produce a
single unified firmware archive while preserving directory layout and symlinks.

This is an additive change and does not modify the existing
templates/boot/fastboot.jinja2 behavior.
