Restore fastboot delete-logical-partition command for VTS

1. delete-logical-partition was deleted
	- After merge "Don't require bootloader fastboot for VTS compliance." commit, delete-logical-partition sequence was deleted in LogicalPartitionCompliance test. "create-logical-partition failed" is occurred when run vts fastbootverification module. So restore this sequence.


Test: run vts -m VtsFastbootVerification
