pgsql: Suppress some compiler warnings in plperl on Windows.

Suppress some compiler warnings in plperl on Windows.

Perl's XSUB.h header defines macros to replace libc functions. Our header
port_win32.h does something similar earlier, so XSUB.h causes compiler
warnings about macro redefinition. Undefine our macros before including
XSUB.h.
