Don't create bookmark files on OSX that start with a dot.

When creating a bookmark file by draging and droping the URL to the desktop
chromium uses the page title for the filename. In cases where the title starts
with a dot the webloc file will also start with a dot. Since files starting
with a dot are considered hidden and not shown by e.g. the Finder users won't
see the expected resulting file. To circumvent this a dot as the first
character is handled like any other character not allowed in a filename and
gets replaced by a hyphen.

BUG=138917
TEST=Paste "data:text/html,<title>. . . hey!</title>" into the Omnibox and drag
  and drop the URL to the desktop.
