pigz: Add pigz to buildtools tarball
When using the tar executable in the buildtools, tar will execute
gzip. If this happens before zlib-native is built, then the gzip
on the host will be used and can fail if the libz in the buildtools
is not compatible. Adding pigz to the build tools avoids this host
contamination.
