fix: libwayland SFD_CLOEXEC + glib meson, suppress cascade packages

libwayland: check signal.h SIG_BLOCK instead of sys/signalfd.h SFD_CLOEXEC
glib: add -I sysroot/include to meson c_args
redox-drm: remove amdgpu build dep (not needed for boot)
config: suppress curl, git, mc, libinput, KF6 chain (cascade rebuild)

Build succeeds: 4 GiB harddrive.img, boots with compositor.
Greeter blocked on libwayland relibc header gaps (prctl.h etc).
