Disable storage crates functionalities

The Storage Crates functionalities is disable by default. In order to
make installd to grow smoothly, the crate function should not add into
installd until it addes more tests such as benchmark and memory regression
tests.

Test: make -j installd && \
        grep crates $OUT/system/bin/installd ; \
        if [ $? -eq 0 ] ; \
        then \
            echo "include crate" ; \
        else \
            echo  "not include crate " ; \
        fi
Test: #should skip the test
      adb root; \
      adb shell setprop fw.storage_crates true \
      atest CtsOsTestCases:android.os.storage.cts.StorageCrateTest \
         CtsOsTestCases:android.os.storage.cts.StorageStatsManagerTest \
         CtsOsTestCases:android.os.storage.cts.CrateInfoTest
Test: #should test fail because installd disable the functionalities
      adb root; \
      adb shell "setprop fw.storage_crates ''" \
      atest CtsOsTestCases:android.os.storage.cts.StorageCrateTest \
         CtsOsTestCases:android.os.storage.cts.StorageStatsManagerTest \
