While this isn't a state you want to be in, I don't think it's as
hopelessly broken as all that. The files that have had .mp_timestamp
appended to their names by forced activation are still tracked and will
be removed when the associated port is deactivated. So all you need to
do to get back to a sane state is deactivate all the conflicting ports
and then activate only one of them. Like so:

sudo port -f deactivate jpeg libjpeg-turbo mozjpeg
sudo port activate jpeg

And then you probably want to rev-upgrade just in case anything ended up
linked with one of the now-inactive ports:

sudo port rev-upgrade
