Lsof improvements (show deleted as in lsof output) + files_only argument

[SolitudePy]

Improvements for Lsof to show deleted files as in lsof output on live system. its probably shouldnt be in that function directly as its no longer mimic prepend_path kernel function this PR breaks commit 68b51e873fe99ffcbf1679f25a9767774b9da3e2 but it can easily be fixed if desired.
