Remove FUSE logic; it's only a sdcardfs wrapper.

Leaving the FUSE logic intact was confusing to OEMs, who expected
that it would still work and pass CTS.  Remove all the FUSE logic
and leave a comment block about why the wrapper exists.

Also use new Android.bp makefile format.

Test: builds, boots
