Remove redundant handling of the default_browser_setting_enabled policy.

While the default browser infobar should be suppressed when policy is
used to enforce defaultness, there is no need to handle the policy in
the infobar as it is already fully handled in BrowserProcessImpl.

BUG=531649
TEST=Verify that all settings of
https://www.chromium.org/administrators/policy-list-3#DefaultBrowserSettingEnabled
work properly. If the policy is set (either enabled or disabled), the
default browser bar should not appear. On Windows 7, Chrome should
become the default browser at startup when the policy is enabled. If the
policy is unset and Chrome is not the default browser, the default
browser infobar should appear.
