mac: Update signature of ShowOneClickSigninDialog() to match declaration.

The declaration was changed in http://codereview.chromium.org/9592015,
but the mac implementation wasn't updated.

TEST=Add -all_load to the linker flags.
__Z24ShowOneClickSigninDialogP7ProfileRKSsS2_S2_ doesn't show up in the
missing symbols list.

This currently happens to work because ld doesn't load .o files from static
libraries if it needs none of the symbols of that .o file (see e.g.
https://plus.google.com/u/0/101038813433650812235/posts/fTuNakqTjGh ). For the
mac components build, we need to add -all_load to our ld lines.

(It's also more correct.)

Thanks Nico!  Fred will be working in the Mac UI shortly and was going to
address this at that time.
