Make --force-fieldtrials not activate them in the browser process.

This is to make this testing flag more consistent with what happens
with a server-side field trial, so that the field trial doesn't
appear in about:version until client code explicitly queries its
state via a group() call.

Does not change the behaviour of the --force-fieldtrials flag
when passes to the renderer process, where it does need to
activate the trials so that they show up in crash reports, etc.

BUG=255142
TEST=Start a debug build of Chrome with the command line
flag --force-fieldtrials=Bat/Man/ and check that it doesn't
show up in chrome://version.
