git2go: Refactor featureflag subcommand to not use raw flags

The featureflag subcommand is only used for testing purposes to assert
that we can indeed pass feature flags from the `git2go.Executor()` to
the process we're about to spawn. We're using raw feature flags for this
purpose, but we're about to remove them in favor of using the type-safe
`FeatureFlag` structure.

Convert the subcommand to return a new `FeatureFlag` structure that we
can use to more thoroughly check whether things behave as expected and
remove usage of `RawFromContext()` to prepare for its removal.

Note that while this is a breaking change to the calling interface of
the `gitaly-git2go` executable, this command is only ever used in our
tests. So in practice, this doesn't matter.
