TestScript is very slow on Plan 9 because this test
is particularly i/o intensive.
This is leading the plan9/386 and plan9/amd64 builders
to time out. This test was already skipped on plan9/arm
because arm is part of the "slow architectures" list.
This change skips TestScript on Plan 9 on short mode.
