Fix usage flags for testWrapHardwareBufferHoldsReference

Fixes an issue where the test was doing CPU access to a gralloc
buffer that did not have CPU_USAGE_WRITE_RARELY set. On some gralloc
implementations it's valid for locking such a buffer to fail, so 
fix the test to conform to gralloc's contract and set the CPU_USAGE_WRITE_RARELY bit.
