    libc: tests: add static to resolve -Wmissing-prototypes

    The function create_staticobj() is only used inside this translation unit.
    Clang produces a -Wmissing-prototypes warning during standard buildworld.
    This warning will become a fatal compile error if MK_WERROR is enabled for
hardened builds.
