arch/kwin-fourier: switch active patch to upstream-shape 0002

0002-transaction-poll-dmabuf-fd-directly-upstream-shape.patch is the
form we'll be sending to invent.kde.org/plasma/kwin (see
upstream-submissions/kwin-fourier/kde-mr-body.md). Same observable
behavior as 0001 (skip the EXPORT_SYNC_FILE round-trip), cleaner
shape: dup() the dmabuf fd and hand it to TransactionFence directly
instead of bypassing the wait entirely.

0001 is kept on disk for reference; carry could revert to it if the
upstream-shape MR runs into review issues.
