Move gensquashfs specific code from libfstree to gensquashfs

The "from dir" and from "from file" code, as well as the "sort file"
code is specific to gensquashfs, so move them there and the test
cases as well.

The medium term idea is to reduce libfstree to a stub, merge it into
the generic writer and ultimately hoist that into libsquashfs.
