bash 5.1: don't rely on patch timestamps in build
When, after patching, `configure.ac` is newer than `configure`, the
Makefile will try to regenerate `configure` from `configure.ac`.

While that might usually be desirable, in this case we want to keep
bootstrapping simple and directly use the `configure` from the package
so we can avoid a dependency on automake.

Previously, we used the `-T` parameter to automake to make sure the
timestamps were okay. However, this is brittle when we update: when the
timestamp of the original file changes, and no longer matches the
timestamp of the original file in the patch, `patch` will show a warning
but otherwise continue without updating the timestamp.

This PR changes things so we only patch `configure`, so that will always
have a newer timestamp.

We will update bash-4.4 in a separate PR (but that one has a bigger rebuild
impact so will have to target staging)
