Root cause of the recurring line-duplication corruption (duplicate #include
<sys/ioctl.h>, nested #if QT_CONFIG(opengl), duplicate assert.h): several of the
recipe's in-place source-munging steps were NOT guarded, so on a committed
(vendored) source/ they re-applied every cook and accumulated. Guard the four
unguarded ones (qwaylandclientbufferintegration opengl-wrap, qnet_unix ioctl
include, corelib CMakeLists REDOX storageinfo block) with grep/marker checks so
re-running on an already-patched tree is a no-op. The rest were already guarded
or naturally idempotent (text.replace consuming its needle).
