Despite the documentation, "etcupdate extract" handles -D destdir (and its contribution to the default workdir)

Thanks, it was a documentation oversight I've just fixed.  It is definitely
supposed to work and is quite useful for cross-builds (e.g. I use it frequently
to update rootfs images I use with qemu for RISC-V or MIPS that I run under
qemu, or when updating the SD-card for my RPI that I cross-build on an x86
host).
