Remove the rebase.useBuiltin setting, which was added as an escape
hatch to disable the builtin version of rebase first released with Git
2.20.
See [1] for the initial implementation of rebase.useBuiltin, and [2]
and [3] for the documentation and corresponding
GIT_TEST_REBASE_USE_BUILTIN option.
As noted in [4] the test suite hasn't passed with
GIT_TEST_REBASE_USE_BUILTIN=false since c762aada1a ("rebase -x: sanity
check command", 2019-01-29). We could fix this as we did for another
such bug in 7e097e27d3 ("legacy-rebase: backport -C<n> and
--whitespace=<option> checks", 2018-11-20), or just decide that the
built-in version is stable enough, and remove the legacy version. This
patch implements that removal of the legacy version.

Here is approach #3, intended for 2.21, but I'll defer to Junio on
whether we should take that approach.
