[S] Change in pysim[master]: filesystem: use sort path when selecting an application

laforge has submitted this change. ( https://gerrit.osmocom.org/c/pysim/+/35351?usp=email ) Change subject: filesystem: use sort path when selecting an application ...................................................................... filesystem: use sort path when selecting an application The method build_select_path_to uses the internal file system tree model to find the path to a given file. This works the same for applications (ADF) as it works for normal files (EF/DF). However, an application can be selected anytime from any location in the filesystem tree. There is no need to select a specific path leading to that application first. This means that if there is an ADF somewhere in the resulting inter_path, we may clip everything before that ADF.
