python-ldtp doesn't work well with double called apps

[Dave Morley]

If your application calls an env or other application to run it then the process monitoring stuff in ldtp will not find it.

Steps to reproduce:
ldtp.getmemorystat('xchat') works as it is "/usr/bin/xchat" in the process queue ldtp.getmemorystat('software-center') fails as it is "/usr/bin/python /usr/bin/software-center".

Expected Results:
I expect to see results for both.
