media-video/mpv: update live

meson.build was updated to only enable shaderc for windows builds
given anything else will use libplacebo, so let's just leave
the setting alone now.

shaderc can now technically be avoided entirely with
libplacebo[glslang,-shaderc], albeit shaderc is still what
upstream libplacebo prefers at the moment (aka in the event
both are available, it'll force shaderc).
