Mac: don't import Safari's home page setting.
Mac: don't import Safari's home page setting.

Apparently it often leads to a useless home page. I kept the ImportHomepage() method in case we ever change our minds.

BUG=25603
TEST=Set the home page in Safari to something interesting; run Chromium with --first-run to bring up import dialog; select Safari and continue; make sure home page isn't imported.
