Fix proc_maps_linux compile for non-Linux

I'm compiling the processor code with mingw, and the new proc_maps_linux code doesn't build there because it's not including inttypes.h on all platforms. Additionally, I think the toolchain I'm using is being stricter and requires __STDC_FORMAT_MACROS to get the macros we're using out of inttypes.h.

This doesn't seem to work on Chromne anymore. Errors below. breakpad is now into
an unrollable state.
