Audit for more mismatched PRIu64 - PRId64 usage

[classilla]

Due to clashing definitions with 10.4's /usr/include/inttypes.h we were using the wrong PRI*64 macros for the libgcc included with gcc 4.8, which caused some printfs to fail. This caused a very hard to diagnose failure in JavaScript code coverage, among other places. This is now corrected in mfbt/IntegerPrintfMacros.h but we need to check that this is actually being used rather than the now defective macro in the original <inttypes.h>.

Here's a set of candidates for PRIu64:
