ui: remove commands.status.terse=u from ui.tweakdefaults

commands.status.terse=u can add significant overhead when operating
on large repositories. Using the Firefox repository:

HGRCPATH= hg --time status
time: real 1.340 secs (user 0.960+0.000 sys 0.380+0.000)

HGRCPATH= hg --time --config commands.status.terse=u status
time: real 2.420 secs (user 2.070+0.000 sys 0.360+0.000)

HGRCPATH= hg --time --config extensions.fsmonitor= status
time: real 0.080 secs (user 0.050+0.010 sys 0.040+0.000)

HGRCPATH= ~/src/hg/hg --time --config extensions.fsmonitor= --config commands.status.terse=u status
time: real 2.470 secs (user 2.080+0.000 sys 0.390+0.000)

The performance regression - especially when fsmonitor is being
used - is too much to stomach for the 4.7 release. We've decided
to remove commands.status.terse=u from ui.tweakdefaults until we
can improve its performance, hopefully in the 4.8 cycle.

This commit effectively backs out 6acf41bb8d40.
