Support copy-on-write persistent data block when running a DSU

The persistent data block is protected by a copy-on-write scratchpad when
running a Dynamic System Update (DSU). The copy-on-write scratchpad
uses a backing file for write operations. This CL adds permissions
to write the backing file for the PersistentDataBlockService.

Bug: 175852148
Test: gsi_tool install & vts_kernel_net_tests
