erofs-utils: Set mkfs default blocksize based on current platform
Set mkfs default blocksize to current platform pagesize.
This means mkfs with default options will work on current
platform. If we are building image for a platform for a different
blocksize, we can override default with -b option up to
EROFS_MAX_BLOCK_SIZE.
