UPSTREAM: ANDROID: fuse-bpf: Follow mounts in lookups

Browse source 
Bug: 292925770
Test: fuse_test run. The following steps on Android also now pass:

	Create /data/123 and /data/media/0/Android/data/45 directories
	Mount /data/123 directory to /data/media/0/Android/data/45 directory
	Create 1.txt under the /data/123 directory

	File 1.txt should appear in /storage/emulated/0/Android/data/45
