Use inttypes.h if stdint.h is not available

Humm.  We cannot meaningfully use the HAVE_* macros there.  It would work in Pango, but not in upstream harfbuzz, since that header will be included by harfbuzz users.  Perhaps we should detect what header defines the int types and include that in a generated hb-config.h or something.

FWIW, pixman has this:

    #if !defined (PIXMAN_DONT_DEFINE_STDINT)

    #if defined (_SVR4) || defined (SVR4) || defined (__OpenBSD__) || defined (_sgi) || defined (__sun) || defined (sun) || defined (__digital__) || defined (__HP_cc)
    #  include <inttypes.h>
    /* VS 2010 (_MSC_VER 1600) has stdint.h */
    #elif defined (_MSC_VER) && _MSC_VER < 1600
    typedef __int8 int8_t;
    typedef unsigned __int8 uint8_t;
    typedef __int16 int16_t;
    typedef unsigned __int16 uint16_t;
    typedef __int32 int32_t;
    typedef unsigned __int32 uint32_t;
    typedef __int64 int64_t;
    typedef unsigned __int64 uint64_t;
    #elif defined (_AIX)
    #  include <sys/inttypes.h>
    #else
    #  include <stdint.h>
    #endif

    #endif

so that is good enough for everywhere X11 runs.

Thanks, I committed the original patch to Pango, and Søren's to HarfBuzz upstream.
