libsepol: fix -Wwrite-strings warnings

When compiling with -Wwrite-strings, clang reports some warnings like:

    module_to_cil.c:784:13: error: assigning to 'char *' from 'const
    char [5]' discards qualifiers
    [-Werror,-Wincompatible-pointer-types-discards-qualifiers]
                    statement = "type";
                              ^ ~~~~~~
    module_to_cil.c:787:13: error: assigning to 'char *' from 'const
    char [5]' discards qualifiers
    [-Werror,-Wincompatible-pointer-types-discards-qualifiers]
                    statement = "role";
                              ^ ~~~~~~

Add a const type attribute to local variables which only handle constant
strings.
