Update KeystoneRegistration.framework to 1.2.0.7671

Update KeystoneRegistration.framework to 1.2.0.7671.

The big change in this version is that an installation attempt initiated
by the application can show up as ondemand on the server. This will
allow us to provide throttled Mac downloads (such as a "5% push") with
correct behavior.

A previous registration framework, 1.2.0.6782, intended to fix this bug
was backed out (via DEPS) because it was not compatible with older
installed Keystones. This version contains a fix for that problem.

Another previous registration framework, 1.2.0.7407, was backed out
because it contained bugs in its installer.

chrome/browser/mac/keystone_registration.h:64: - (BOOL)setActive;
setActive is still (void) in 7671. (The change to BOOL is done after this build
was made)

Ignore my comment... this actually got in. So this code is correct.
