Unset emsdk-related environment variable from inactive tools (#801)

When we deactivate a tool we also want to remove its environment
variables.   One driver for this is that modern sdks don't set
`EM_CACHE` whereas old ones did and we want to make sure that
`EM_CACHE` gets unset when folks upgrade (and then re-set if
they downgrade).  See #797.
