pstat(8): display text for msts/endrun line disciplines

[Iain R. Learmonth]

ping.

pstat(8) will display text description for the nmea line
discipline, but not for msts/endrun. This patch adds support
for displaying text for msts and endrun line disciplines in
the output of pstat -t.

comments? ok?
