git: skip Rust bits in i686 builds (again)

This was already done as part of b08d188 (mingw-w64-git: upgrade to
Git for Windows 2.55.0 (msys2#30227), 2026-06-29), but was inadvertently
reverted in the parent commit because I had forgotten to merge
#207 in the hectic
release process before building the artifacts of Git for Windows
v2.55.0(2).
