Speculatively revert 50374 (miniinstaller breakage) - Load netinternals resources from resources.pak.

This is the same as r50257 with 2 fixes:
1) Copy resources.pak to <(PRODUCT_DIR) on mac so it will
work for things tests.
2) Add back the check in chrome_paths.cc to see if we're in a
mac bundle or not.
