cmd/vendor, cmd/pprof: use golang.org/x/term directly

Browse Source 
The cmd/pprof package currently uses golang.org/x/crypto/ssh/terminal
which - as of CL 258003 - is merely a wrapper around golang.org/x/term.

Thus, drop the dependency on golang.org/x/crypto/ssh/terminal and use
golang.org/x/term directly.
