Bug 1357873 - Fix up 64-bit Android macros in IntegerPrintfMacros.h; r=Waldo

Browse source 
On 64-bit Android, the inttypes.h macros for [u]int_fastN_t types (e.g.
int_fast16_t) use "d", "u", etc. as the format specifier, but the types
themselves are defined as `long`, `unsigned long`, etc. This patch
redefines the macros as `PRId64`, `PRIu64`, etc. to provide correct
behavior.
