Attach format attributes to declarations of various message-formatting

routines under gcc.  In a couple of routines, hard-code the preference
for using the vsnprintf paths instead of list-of-int-arguments hacks
now that we're assuming vsnprintf is available in other places.

Installed headers affected:
  com_err.h (com_err, com_err_va)
  ss.h (ss_error)
  krb5.h (krb5_set_error_message, krb5_vset_error_message)
