include demangle(1) in Gimlet image

[jclulow]

As it says on the tin, it would be helpful if, at least for now, we could include demangle in the OS image. This program presently ships in the /developer/object-file package:

$ pkg search file:basename:demangle
INDEX      ACTION VALUE            PACKAGE
basename   file   usr/bin/demangle pkg:/developer/object-file@0.5.11-2.0.22112

This includes a bunch of other stuff we probably don't need...

 $ pkg contents -t file /developer/object-file | grep -v usr/share/man
PATH
usr/bin/amd64/ar
usr/bin/amd64/elfedit
usr/bin/amd64/mcs
usr/bin/amd64/nm

usr/bin/dis

usr/share/lib/ccs/nceucform

usr/share/lib/ccs/yaccpar

But the overall increase is not that large, so we should probably just whack it in there:

 $ pkg contents -H -t file -o path,pkg.size developer/object-file | grep -v usr/share/man | awk '{ q += $2 } END { print(q / 1024 / 1024); }'
