fix: libwayland BUILDS — proper durability patch with all stubs

121-line redox.patch replaces 229-line fragile Python heredoc.
Covers: meson.build, src/meson.build, event-loop.c, connection.c,
wayland-server.c with signalfd, timerfd, eventfd, MSG_NOSIGNAL,
open_memstream, timerfd_settime, timerfd_gettime stubs.

libwayland builds successfully. Greeter cascade through llvm21.
