mac: Fix omnibox size after r156836

mac: Fix omnibox size after r156836

Window coordinates aren't pixels on 10.7+, so this code isn't
necessary at all. (This CL breaks the omnibox on 10.6 with user
space scale factor, but that's not a supported configuration
anyway.)

BUG=149826
TEST=omnibox looks good on retina
