filesystem: add flag to tell whether an ADF supports an FS or not

An ADF may or may not support a file system. For example ADF.ARA-M does
not have any filesystem support, which means the SELECT we may use from
this ADF is limited and an can only select a different application. To
know about this in advance let's add a flag that we set when we
instantiate an ADF.
