vcsh: Do attempt docopts install on aarch64

As it turns out, docopts _does_ have an ARM build, but it doesn't
download it when the architecture is reported as aarch64. I opened
a pull request against docopts and I hope it will be merged. In
anticipation of the merge and subsequent release, I'm removing the block
against aarch64 downloads now.
