Subject: meson: make non-symlink scripts install for real, and use a better
 wrapper

We now generate the scripts using their real name, install them using
meson's builtin facility instead of an install_script, and generate the
wrapper scripts in the root of the build directory, instead of a
subdirectory.

This gets us closer to resolving FS#64394.
