makepkg-git-i686: accommodate for gettext v0.23.*

As of v0.23, the `msgfmt.exe` program depends on a newly-introduced
library, gettext-libtextstyle. In e70ecb7 (minimal-sdk: accommodate
for gettext v0.23.*, 2025-01-07), we included that in minimal SDK's
sparse checkout, too.

But we forgot to update the `makepkg-git` sparse definition for building
the i686 variant of `mingw-w64-git`. This did not cause problems during
the v2.48.0-rc phase so far because the `git-artifacts` workflow builds
the i686 variant in the i686 Git SDK.

However, the Azure Pipeline that builds the snapshots (and which I
haven't found time to migrate to GitHub Actions in the past two years)
still used the x86_64 Git SDK to build the i686 variant of
`mingw-w64-git`, and there things fell apart.

So let's fix this.

In the long run, we will want to stop building i686 packages in the
x86_64 Git SDK altogether.
