Execute script, used to get system calls of docker during execution

Hello, When I use the systemTap4.4 version to test on an Ubuntu system with a
kernel version of 4.4.0-21, the following problems occur.

Then, I searched for a related answer(Bug 24720) that said it was a problem
with guru mode. But the C language code is embedded in my script, so I need to
turn on the guru mode. If it is not turned on, an error will occur
