Makefile: thin shims only, add make build (closes #73)
The Makefile is now one shim per script/ entrypoint, in the order of
the canonical model Makefile, plus build, generate and fuzz. The new
script/build writes bin/mfer with the urfave_cli_no_docs tag and the
git describe revision that script/docker stamps. script/generate now
adds the Go bin directory to PATH itself, and the Docker lint stage
calls script/gofumpt --check directly. Removed: the tarball-caching
rules and their ignore entries, godoc, ci, fixme, clean, run, default,
fmt-check-go, fmt-check-md, and bin/gitrev.sh, which only the
Makefile called.

# script/generate: regenerate mfer/mf.pb.go from mfer/mf.proto, and record
# the hash of that mf.proto in mfer/mf.proto.sha256. Nothing else
# regenerates mf.pb.go: it is committed, so building and checking need no
# protoc. A test fails while mf.proto no longer matches the recorded hash.
#
# Needs exactly the protoc and protoc-gen-go versions named in the header of
# the committed mf.pb.go (README.md says how to install them). Another
# version writes a different mf.pb.go, so the script refuses to run.
