[NTP] Adding mathp@ as owner of components/search

Few reasons for this:
- My team and myself are now owners of the feature
- Both current owners are gone through the end of July
- I am owners of other parts of the NTP code (resources, data sources) as well
  as server-side code; as such, I think I'm qualified.
