ANDROID: fuse-bpf: Introduce readdirplus test case for

Safae Ouajih requested to merge souajih/android_k into integ/ti-android-5.10.y

fuse bpf

Readdir plus is potentially dangerous place because this leads us to allocate fuse inodes. If we have problems with inode allocation and discovery we may end up with inode conflict which may cause backing_fd losing.

We currently have this problem and this test clearly reproduce it.
