t/zbd: Use max-jobs=16 option

Use max-jobs option to reduce memory usage and speedup execution of
test-zbd-support.

With --max-jobs=16, twice the largest number of jobs used in all test
cases, the execution time of test-zbd-support against a zoned nullblk
device is lowered from 64s to 41s on a laptop.
