The error message when destroying a held snapshot no longer is `dataset
is busy` but `it's being held. Run 'zfs holds -r <snapshot>' to see
holders.`
The existing `destroySnapshotsErrorRegexp` parses both formats
correctly, but downstream test assertions in platformtest were checking
for the literal `dataset is busy` string.

A number of tools including `lnav` do a crude string matching against
the word "error". For zrepl this results in benign lines being colored
red. It would be better if the logged message was something like
"command ran successfully".
