sflow_agent: Use snprintf() in place of sprintf().
These functions use sprintf() into a 1000-byte buffer. It appears to me
that the strings they format are either short, fixed-length strings or the
output of strerror(), neither of which should ordinarily overflow.
However, using snprintf() cannot hurt.
Launchpad bug #914160.
