Remove profilePathOnHost from bootImageConfig

Browse source 
The use of this field to return information from bootImageProfileRule
up the call stack to one of the users resulted in data races being
detected. This change simply returns the profile path back up the call
stack.

Bug: 245956352
Test: m nothing
      go test -race ./sdk/... -run TestSnapshotWithBootclasspathFragment_ImageName -test.count 100
      # Run the previous command without this change and sometimes it
      # shows the data race around profilePathOnHost. With this change
      # that data race is not reported. Although there is still another
      # data race.
