Fix multiple instances of the following clang 3.6.0 warning in ppp:

usr.sbin/ppp/command.c:2054:74: error: address of array 'arg->bundle->radius.cfg.file'
will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion]
      if (arg->bundle->radius.alive.interval && !arg->bundle->radius.cfg.file) {
                                                ~~~~~~~~~~~~~~~~~~~~~~~~~^~~~

In all cases, the file field of struct radius is a char array, but the
intent was to check whether the string is empty, so add an indirection
to achieve that.  Use a similar approach for the sockname field of
struct server.
