[dts] [V1] framework/*: modify command line that list opened files

[Jun Dong]

In some framework scenario, needing to use lsof command to query opened 
files that occupied specific ports and to do something about the it. now
add -n options to the command to skip reverse resolution of domain name
when querying to avoid timeout in network offline env.
