[PATCH 09/10] transport-helper.c: convert trivial snprintf calls to xsnprintf

[Elia Pinto <gitter.spiros@gmail.com>]

With the commits f2f02675 and 5096d490 we have been converted in some files the call
from snprintf/sprintf/strcpy to xsnprintf. This patch converts the remaining calls
to snprintf with xsnprintf under the following conditions:

- The call to snprintf does not control the outcome of the command
  or the presence of truncation errors.
- A call to snprintf can generate a fatal error, directly or indirectly.

The other few remaining cases in which a call to snprintf can generate a soft error
have not been changed.
