x86, build: move build output statistics away from stderr
When building on x86, the final image building step always emits stats to stderr, even though this information is neither a warning nor an error: BUILD arch/x86/boot/bzImage Setup is 16188 bytes (padded to 16384 bytes). System is 6368 kB CRC cbe50c61 Validating automated builds would be cleaner if stderr did not have to filter out these lines. Instead, change how tools/build is called, and make the zoffset header unconditional, and write to a specified file instead of to stdout, which can then be used for statistics, leaving stderr open for legitimate warnings and errors, like the output from die().
