derive_builder: Use git dep everywhere, rather than cargo patch

The `[patch]` approach causes the tree not to build when used as a
dependency, unless the `[patch]` is replicated into the depending
project.

Instead, replace our `derive_builer =` dependencies with a reference
to a specific git commit:

  perl -i~ -pe 'next unless m/^derive_builder/; s#"(0\.11\.2)"#{ version = "$1", git = "https://github.com/ijackson/rust-derive-builder", rev = "ba0c1a5311bd9f93ddf5f5b8ec2a5f6f03b22fbe" }#' crates/*/Cargo.toml

Note that the commitid has changed.  This is because derive_builder is
in fact a workspace of 4 crates.  3 of them are of interest to arti
itself (the 4th exists only for testing).  So the same "add git
revision" treatment had to be done to the `derive_builder` and
`derive_builder_macro` crates.  Each dependency edge involves a new
commit in the derive_builder workspace, since we can't create a git
commit containing its own commitid.  (We want to use commits, rather
than a branch, so that what we are depending on is actually properly
defined, and not subject to the whims of my personal github
namespace.)

There are no actual code changes in derive_builder.
