dont install PPPort.so/PPPort.dll

This shared lib is only used for PPPort testing itself, it is similar to
APItest.dll in purpose. PPPort.pm never uses XSLoader/DynaLoader, only its
.t files do. This saves 616KB in the final install dir on Win32, and
atleast one or two dozen KB on all OSes. Since where is auto dir, and what
is arch dir, is complicated and unportable (atleast to me), and what other
files live next to the shared lib (examples, .pdb file, .bs file, .a file)
match the directory fragment, not the files inside of it or the dirs
full path.
