Ricardo Pardini eab306b279 tmpfs: introduce USE_TMPFS=no to disable tmpfs usage for WORKDIR and package-specific working dirs; actually use $temp_dir_id for mktemp; see #5502
- `USE_TMPFS=no` disables usage of generic tmpfs mechanism (still possibly used for rootfs/image building, which is unrelated), for last-resort cases
- use better/more descriptive `temp_dir_id`'s for kernel build than `k` (now `kernel_dest_install_dir`) and `kd` (now `kernel_debs_temp_dir`)
  - specific image/dtb/headers packaging already had decent names, same for other .deb's
- replace `mktemp -d` with `mktemp -d --tmpdir "${temp_dir_id}-XXXXX"` in `prepare_temp_dir_in_workdir_and_schedule_cleanup()`, so we know what's using what in tmpfs
