    meson: Always build with hidden symbol visibility
    
    This copylib isn't intended to be part of anyone's ABI. In Autotools,
    this is typically implemented by doing some ad-hoc compiler checks and
    adding -fvisibility=hidden to the global CFLAGS of any library that
    pulls in libglnx, but in Meson it's a build system feature.
