libselinux: add a const to suppress a build warning with Python 3.7

Browse Source 
On systems using Python 3.7, when compiling libselinux Python wrappers
(with "make install-pywrap"), the following warning is reported by gcc:

    audit2why.c: In function ‘analyze’:
    audit2why.c:364:11: warning: assignment discards ‘const’ qualifier
    from pointer target type [-Wdiscarded-qualifiers]
       permstr = _PyUnicode_AsString( strObj );
               ^

Make permstr "const char *" in order to suppress this warning.
