add better compatibility to find libxml2js and for M1 CPU

[Raffaello]

Hi,

using libxml2-xsd on M1 chip is returning error:

clang: error: no such file or directory: '[...]/node_modules/libxmljs2/build/Release/xmljs.node'
npm ERR! make: *** [Release/node-libxml-xsd.node] Error 1

This issue is resolved removing libxmljs2-xsd from the package.json file and install its own dependency libxmljs2 after doing the install,

restore the package.json and re-adding the libxmljs2-xsd is successful.

could you please be investigate on an M1 chip and fix it?
