Kacper Michajłow baabc291f1 build: fix dynamic generation of mpv.desktop file protocols
Running cross-compiled binaries may be possible, but the runtime
environment must be configured correctly. In some configurations, an
exe_wrapper needs to be used, and in all cases, the library path must be
set correctly for the given binary. Fortunately, Meson handles all of
this if cross-compilation is configured correctly.

Fix this by having Meson run the mpv binary directly, instead of as a
subprocess of a Python script. This ensures that the environment is
properly set for running host binaries, if possible.

Fixes: #15075
