[groff] [PATCH] Remove unnecessary randomness from example output

[Colin Watson]

The hdtbl examples don't need good randomness, as they're only
example output; removing the process ID from consideration allows
better integration with reproducible builds.

* contrib/hdtbl/examples/common.roff (random-s1): Remove process ID.
