tests: don't expect $EGREP to support -w

Does not work on Solaris 10.  Reported by Dennis Clarke.
http://lists.gnu.org/archive/html/bug-bison/2012-11/msg00009.html
* tests/headers.at (Several parsers): Use Perl instead.
While at it, run it only once, on all the generated headers.
Adjust to YY_NULL be defined in position.hh.
