Process: highlight UNINTERRUPTIBLE_WAIT state (D)

Commit d8dfbbd3 ("Tidy up process state handling") did change the
highlighting of the UNINTERRUPTIBLE_WAIT state (D) from red to gray.
As this state might means the process probably still has work to do and
can hint at bottlenecks, revert this particular change.

Fixes: d8dfbbd3 ("Tidy up process state handling")
