If we're not on a branch, e.g. if we've checked out an arbitrary
revision, then 'git branch --show-current' sensibly won't give us any
output, and thus the pills produced by sh/create-ropsten-pills will be
misnamed.
Consuming HEAD with git-rev-parse has the same effect here, and should
work in all cases of interst.
This removes the baked in codedump inspection and wrapper scripts
in favour of downstream tooling overriding this as necessary by
using FROM <image> in their respective dockerfile.
Rather than conditional reconstructing the "urbit/bin/urbit-debug -g"
string everytime using the debug conditional, this information has been
added to the derivation's .meta attribute.
