[lldb][NFC] Remove strange bool parameter from Searcher::SearchCallback

Summary:
The SearchCallback has a bool parameter that we always set to false, we never use in any callback implementation and that also changes its name
from one file to the other (either `containing` and `complete`). It was added in the original LLDB check in, so there isn't any history what
this was supposed to be, so let's just remove it.
