Keep a local copy of the symbol name in the symbol table

The symbol_header structure that tracks symbols with a particular name
may have a different (longer) life time than the symbols it tracks.
Not keeping a local copy of the name can lead to use-after-free
errors.  For example, the following sequence would trigger such an
error:

    char *copy = strdup(name);

    _mesa_symbol_table_push_scope(st);
    _mesa_symbol_table_add_symbol(st, 0, name, NULL);
    _mesa_symbol_table_pop_scope(st);
