[PATCH 3/6] libsepol/cil: fix -Wwrite-strings warning

[Nicolas Iooss <nicolas.iooss@xxxxxxx>]

cil_defaults_to_policy() defines its third argument as non-const "char
*kind" even though it is called with literal strings. This makes gcc
report the following warning when compiling with -Wwrite-strings:

    ../cil/src/cil_policy.c: In function ‘cil_gen_policy’:
    ../cil/src/cil_policy.c:1931:60: error: passing argument 3 of
    ‘cil_defaults_to_policy’ discards ‘const’ qualifier from pointer
    target type [-Werror=discarded-qualifiers]

      cil_defaults_to_policy(out, lists[CIL_LIST_DEFAULT_USER],
                             "default_user");
                             ^~~~~~~~~~~~~~
