Conversation
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. Signed-off-by: Tharun Kumar Merugu <mtharu@qti.qualcomm.com>

Summary
This PR adds a new LAVA fastboot template:
templates/boot/fastboot_fastrpc.jinja2The template is intended for FastRPC-specific jobs where firmware is supplied as multiple archives and needs to be combined during post-processing.
Motivation / Background
We observed LAVA failures during post-processing when firmware archives were combined using
cat. Simple concatenation does not properly merge the archives’ filesystem structures. This can break early-boot firmware loading when symlinks and firmware placement span multiple archives.Issue Observed
When two firmware archives are concatenated:
/libsymlink provided by one archive may not resolve to firmware files supplied by the other archive./lib/firmware, resulting in firmware load failures.Failing LAVA job (cat-based merge): Job LAVA | Scheduler | Jobs | 41792
Working LAVA job (extract+repack merge): Job LAVA | Scheduler | Jobs | 41841
