Use mode_t, not int, for umask return/argument value

Fixes clang warnings:

auth.c:144:22: warning: implicit conversion changes signedness: 'mode_t' (aka 'unsigned int') to 'int' [-Wsign-conversion]
    original_umask = umask (0077);      /* disallow non-owner access */
                   ~ ^~~~~~~~~~~~

auth.c:214:12: warning: implicit conversion changes signedness: 'int' to 'mode_t' (aka 'unsigned int') [-Wsign-conversion]
    umask (original_umask);
    ~~~~~  ^~~~~~~~~~~~~~
