runtests.py: treat strings within quotes as a single string

[xupengfe]

Treat strings within quotes as a single string:
It could solve the avx512vbmi/tests like "0 ff b" could not be executed by runtest.py.

Hi @xupengfe , appreciate your quick response. I have another implement for this issue, that is more "python style"
please review: #317

Hi @ysun ，
I was the first to fix this problem, and according to community guidelines, the maintainer can suggest improvements, but the original fix should be acknowledged.

Yes, the cmd line should be parsed together, it's better.
Additionally, your submitted patch does not account for exception cases.

I included you as 'Co-developed-by' and Zhu Haoliang as 'Reported-by'. Would you agree with this approach?
Please check the #318

Thanks!
