    gpgscm: Fix compact vector encoding.
    
    * tests/gpgscm/scheme-private.h (struct cell): Use uintptr_t for
    '_flags'.  This way, '_flags' has the size of a machine word.

    The compact vector representation introduced in 49e2ae65 requires that
    we can tell apart pointers and type flags.  This did not work on
    64-bit big-endian architectures.
    
    Fixes a crash on 64-bit big-endian architectures.
