Fix Sigmet2Dsr build

[ohmer]

Fix Sigmet2Dsr link stage. Sigmet2Dsr is not wired to the repository build infrastructure so did not impact releases.

Tested with make:

~/git/lrose-core/codebase/apps/ingest/src/Sigmet2Dsr$ make clean strip install
/bin/rm -f core a.out
/bin/rm -f *.i *.o  *.ln *~ *.mod
strip Sigmet2Dsr
