[Toybox] [PATCH] timeout.test: reduce flake.

[Rob Landley]

Catching up. (I let stuff pile up preparing for the release and then took a
couple days off, and now I'm at texas linuxfest doing sleep deprived talk prep
for tomorrow...)

Yes it should never happen, but 11 minutes seems like a footgun.

I bumped it up to 1 second (10 times as long as before). If you see it again I
can bump it to 5 seconds, but much beyond 1 second and the "timeout -v .1 sleep
3" test later on gets flaky, as does:

toyonly testcmd "-i" \
  "-i 1 sh -c 'for i in .25 .50 2; do sleep \$i; echo hello; done'" \
  "hello\nhello\n" "" ""
