[PATCH] fix parallel build w/gropdf and mom examples

[Mike Frysinger]

The contrib/mom/examples/ directory uses the helper script from
src/devices/gropdf/.  Currently though, parallel builds might fail
like so:

...

The top level makefile tries to account for this in general with OTHERDIRS,
but looks like src/devices/gropdf/ was added to this variable (which holds
contrib/mom/ too) because gropdf installs a shell script, and the other
prog vars require it to be a dir of things to compile.

Declare a new prog var for holding shell scripts.
