[RFC PATCH v1 2/5] selftests/filesystems: convert fusectl test to fuse3

[Luis Henriques <luis@igalia.com>]

Since it is probably not worth adding new fuse kselftests based on fuse2,
it is a good idea to convert the single existing test to fuse3.  The
conversion is trivial, as it only requires some changes to function
signatures (the gettattr and truncate fuse operations), and to the filler()
helper.
