iotests: Test allocate_first_block() with O_DIRECT
Using block_resize we can test allocate_first_block() with file descriptor opened with O_DIRECT, ensuring that it works for any size larger than 4096 bytes. Testing smaller sizes is tricky as the result depends on the filesystem used for testing. For example on NFS any size will work since O_DIRECT does not require any alignment.
