Taught zdb -bb to print metadata totals
People often want estimates of how much of their pool is occupied
by metadata, but they end up using lots of text processing on zdb's
output to get it.

So let's just...provide it for them.

Now, zdb -bbbs will output something like:

Blocks  LSIZE   PSIZE   ASIZE     avg    comp   %Total  Type
[...]
    68  1.06M    272K    544K      8K    4.00     0.00      L6 Total
