tcpdump/libpcap: correctly declare dependency between lex/yacc

* Previously, debugging jam, it would output a warning along the
  lines of 'warning: using independent target ... grammar.c'. To
  fix the dependency, it needs to be declared from object file
  to the generated source file.
* With the correct dependency (scanner.o on grammar.c), this
  warning is eliminated, and the dependency graph shown is now
  correct
* This should address #4091
