[ci] Drop msys2 keyring workaround

This now breaks because the hard-coded keyring version it tries to
fetch is no longer in the repo, but it no longer seems to be
required (presumably appveyor have updated their image to fix the
problem).

(cherry picked from commit 6d32e27a91c510e96d6f52c9ad4f09179e6edfcf)
