dispatch: set profiling.enabled when profiling is enabled

We do this for other global command arguments. We don't for --profile
for reasons that are unknown to me. Probably because nobody has needed
it.

An upcoming patch will introduce a new consumer of the profiling
code. It doesn't have access to command line arguments. So let's
set the config option during argument processing.

We also remove a check for "options['profile']" because it is now
redundant.
