Kyle Evans f08dac4e90 libbe(3): Don't allow bootfs to be destroyed
Previously, the following sequence of events was feasible under some
circumstance:

bectl create test
bectl activate test
# the test BE dataset gets promoted and set as bootfs
bectl destroy test

I was unable to reproduce the destroy succeeding, but we should be rejecting
this before it even gets to libzfs because it would leave the system in an
inconsistent state. Forcing the user to be explicit as to which environment
should be activated instead is much better.
