pipewire: don't setlocale from pw_init, let parent app set it

Library code generally shouldn't modify global state, so pw_init()
should not result to changing the C locale.

Instead, set the C locale in main() for tools and daemons.

We'll still setlocale for LC_MESSAGES, to get translated UI elements in
wireplumber. This workaround should be removed eventually...
