ASN: Fix default asn compiler path

For your next release (commits) can you replace the default path for asn1.exe and set it to $HOME/tool-inst/share/asn1scc/asn1scc

We have upgraded the tool to build using .NET Core 5 instead of mono, so we do not use/need mono anymore. The executable is not asn1.exe but asn1scc (without extension).

The path has to be set right by default on your side because otherwise on the first installation there is no ~/.config/QtProject/QtCreator.ini file to be patched, and the configuration would be pointing to the wrong file on the first run
