fix: libwayland durability patch replaces fragile Python modifications

Created proper redox.patch (105 lines) that applies to wayland-1.24.0:
- meson.build: SFD/TFD checks → signal.h/time.h
- src/meson.build: wayland-scanner detection
- src/event-loop.c: signalfd/timerfd compat + definitions
- src/connection.c: MSG_NOSIGNAL + open_memstream stub

Recipe simplified from 270-line Python heredoc to clean meson build.
Patch survives make clean, git clone, and upstream rebase.
