cmd: update x/term to pull in CL 316112

Even though x/term is now lazy, this has no overall effect (yet) on
the contents of cmd/go.sum, because the dependency that would be
pruned out (an old version of x/sys) is still transitively required
through x/crypto, x/sys, and/or x/tools.

Once those modules are also lazy (CL 316109, CL 316111, and CL 315570
respectively), the extra go.sum entries for x/sys will drop out.

For #36460
Updates #36905
