lib/oe/rootfs: tidy up log warning reporting

* bb.warn() should only be called once per warning - UIs such as Toaster
  assume that this is the case, so adjust the output accordingly. (It's
  tricky here because we have to include "log_check" on every line or
  we'll end up looping forever as the log checking code's own messages
  retrigger the log check, sigh...)
* Iterating over a file already splits by line, there's no need to do it
  manually.
