feat: add fixed /tmp mount flag#26

Conversation
Add --tmp-host-dir to docker_deb_build.py and mount the provided host directory to /tmp inside the container. This avoids failures on large package builds where the default container /tmp can be memory-backed and too small. The option is build-mode only and now includes path validation, and README documents why and when to use it. Signed-off-by: Simon Beaudoin <sbeaudoi@qti.qualcomm.com>
Replace the previous fixed /mnt flag with a fixed /tmp flag: --mount-host-tmp. When set, docker_deb_build.py bind-mounts host /tmp to container /tmp. This keeps the mount behavior binary and removes user-selected path input. README and usage examples are updated to match this behavior. Signed-off-by: Simon Beaudoin <sbeaudoi@qti.qualcomm.com>

Summary
--mount-host-tmp/tmpto container/tmp--mount-host-tmpin--rebuildmodeWhy
Large package builds can exceed the container's default temporary storage
capacity. This flag gives the build access to host-backed
/tmpspace withoutrequiring a user-selected path.
