[dts] [PATCH] try fix scatter case failed

[Liu, Yong]

Huilong,
The timeout 60s is for foreground commands. You can see in scapy_execute function, dts only wait two seconds after all commands.
I mean whether we should enlarge the timeout value here.

Maybe you can try your solution on more platforms to make sure it can work.
