weston: refuse meson subproject fallbacks

weston ships wrap files for aml, display-info, edid-decode, neatvnc
and perfetto. When a dependency check fails, meson quietly builds the
bundled copy, and Build/InstallDev then stages its library, headers
and pkg-config file over the ones of the real package, which broke
every later consumer of libdisplay-info. Pass --wrap-mode=nofallback
so a missing or unsuitable dependency fails the configure step.
