pp.c: delete dead cpp-conditional declaration

This was added in commit dfe9444ca7881e716e9e8feaf20b55da491363ca (February
1998, for Perl 5.004_60) by Andy Dougherty, and its comment says that, even
then, he thought it was unneeded. But the perl5 repo has ever defined the
NEED_GETPID_PROTO cpp symbol that guards this declaration, so this ability
has clearly never been used.
