This replaces the specific gtkdoc wrapper setting
(which was rejected by upstream in https://github.com/mesonbuild/meson/pull/9627)
with a generic, officially supported and documented exe_wrapper,
which is enabled subject to qemu usermode support
(just as is done for g-i and gtk-doc with autotools).
gtk-doc support is adjusted so that this wrapper is passed to
meson's gtk-doc module, which passes it to gtk-doc.
The adjusted patch is re-submitted upstream.
The side effect of this is that meson is now able to run
target binaries in a generic way when it wants to, so this
may affect cross-builds - hopefully in a positive way.
