[totem] all: Fix compile-time warning with GCC7

[Bastien Nocera <hadess src gnome org>]

commit 3333ea1bbfaf3ef815d97e08863b596b66a51ed0
Author: Bastien Nocera <hadess hadess net>
Date:   Mon Jun 26 12:15:42 2017 +0200

    all: Fix compile-time warning with GCC7
    
    duplicate ‘const’ declaration specifier [-Wduplicate-decl-specifier]
    
    The warning was added in:
    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=43651
    just for this purpose.
    
    "
    int foo(const char const *data);
                       ^~~~~~
    1 warning generated.
    
    [...] In that case it was clearly a mistake, because the author meant
    'const char *const data' [...]
