Ticket History #5507: MITKRB5-SA-2007-002: buffer overflow in krb5_klog_syslog

Fix MITKRB5-SA-2007-002: buffer overflow in krb5_klog_syslog.

* src/lib/krb5/krb/get_in_tkt.c (krb5_klog_syslog): Use vsnprintf
if available.

Everything else: use precision fields on "%s" specifiers to truncate
logged strings, in case someone doesn't have vsnprintf.
