[1/3] manifest: exFAT support

SlimKat has already exFAT support from CM11 but the binaries are not there and it is not enabled.
Since we are using exFAT and fuse binaries from OmniRom, the system/vold needs to be patched.
The complete exFAT sets:
[1/3] manifest: exFAT support
[2/3] vold: exFAT support
[3/3] vendor: exFAT support
