build: version exec-harness and memtrack with the runner

Both ship inside the `codspeed` binary, so their own versions no longer
mean anything. Move the version to `[workspace.package]` and have the
runner, `exec-harness` and `memtrack` inherit it. The integration version
`exec-harness` reports goes from 1.3.0 to the runner's.

They still declare binaries, so opt them out of dist: sharing the runner's
version, a `v*` tag would otherwise release them alongside it.
