kernel: allow write access to /data/misc/vold/virtual_disk

Browse source 
The kernel thread which manages this file really needs read/write access
to this file, not read-only. This was suspected in b/36626310 but
apparently something must have changed in the kernel surrounding
permission checking for kernel threads (still unknown)

Bug: 36626310

Test: policy compiles
