Remove redundant -I..\lib arguments from some Win32 makefile command-lines

Invocations of $(PERLEXE) from win32\ do not need -I..\lib since $(PERLEXE)
is ..\perl.exe, which will pick up the lib\ folder in ..\ anyway.

Invocations of perl.exe from t\ (which may be a copy of either perl.exe or
miniperl.exe from the top-level folder) also do not need -I..\lib since
they all run the harness program, which fixes up @INC with exactly that
..\lib folder in a BEGIN block anyway.
