linuxloader: Convert to python function

Browse Source 
We could do with one decent general purpose python function to query the
path to the dynamic loader. Convert the shell code into python.

Also correct baremetal to return "None", not musl loaders.

(From OE-Core rev: 73fab4ede12d8ae31be72b5cb4ab29d7ef7dae17)
