encore defconfigs update

* DEVKMEM=n: This was accidentally reenabled in 9aee6b8... ("Update
  defconfig").  Unnecessary and frequently used by rootkits.
* FUSE_FS=y: Requested by users, and also needed for emulated /sdcard
  support if anyone wants to play with that.
* HID_{APPLE,ELECOM,MAGICMOUSE,MICROSOFT,SONY,WACOM}=y: Needed for
  support of non-HID-compliant Bluetooth input devices, most notably
  Apple and Apple-clone BT keyboards.  Thanks to XDA user
  cybertimber2007 for helping to track down this problem.
Hmmmm
