[9fans] bringing down vacfs in p9p

[erik quanstrom <quanstro@quanstro.net>]

the unix domain sockets in `{namespace} don't need to be removed;
9pserve -- not vacfs -- creats the socket file. it is not removed,
regardless of how things exit.

since vacfs doesn't do rfork(RFNOTEG), hitting delete in the 9term
window from which vacfs was started should kill vacfs off.

i don't see how that could be dangerous since vacfs is only a cache.
