Bug#891465: glpk: prints warnings which lead to failing sagemath tests

[Mike Miller]

Package: libglpk40
Version: 4.65-1
Followup-For: Bug #891465

Hi, I also see this bug affecting octave, although as a minor cosmetic
issue. Octave's glpk unit tests also intentionally set msg_lev to
GLP_MSG_OFF to have no output generated. With glpk 4.65, this same
message is now appearing in the test suite output log.

It would be very helpful if GLP_MSG_OFF suppressed this message as it
does with other messages.
