autoconf and automake mostly give us this for free, but we do have to
take some care.
This enables out-of-tree builds configured such as:
(cd /obj/snapper && ~/work/snapper/configure ...)
make -C /obj/snapper ...
When the child exits with non-zero status, use it as snapper's own exit
code, as it may be meaningful.
We pass the exit code up the stack with a new CommandException type.
When we can't even run a child process at all (system(3) returns -1),
throw runtime_error_with_errno without taking the post snapshot.
When the child is killed or exits with non-zero status, report that to
stderr and exit(EXIT_FAILURE) .
