Meson will now set the MESON_EXE_WRAPPER as the properly wrapped and joined representation. For Unix-like OSes this means python's shelx.join, on Windows an implementation that attempts to properly quote windows argument is used. This allow wrapper scripts to run test binaries, instead of just skipping.
for example, if the wrapper is ['emulator', '--script'], it will be passed as MESON_EXE_WRAPPER="emulator --script".
