[PATCH 1/2] libselinux/utils: add noreturn attribute to selinux_check_access's usage

[Nicolas Iooss]

When building libselinux, clang reports the following warning:

    selinux_check_access.c:8:1: error: function 'usage' could be
    declared with attribute 'noreturn' [-Werror,-Wmissing-noreturn]

While at it, make progname const.
