the dbuild script provided by the branch being debugged might not
include the recent fixes included by current branch from which
`open-coredump.sh` is launched.
so, instead of using the dbuild script in the repo being debugged,
let's use the dbuild provided by current branch. also, wrap the
dbuild command line. for better readability.
