Allow %x and %? to be used in errorcmd.

When `cmd` fails, the only clue as to why can be its exit code.
Previously, snare had no way of transmitting this information to the
user: this commit allows using `%x` and `%?` (the latter borrowing the
similarly named variable from the shell) to in `errorcmd` to access this
information.
