bitbake: event: Remove duplicated items from close matches

It printed duplicated ones when there are multiple similar recipes in
differrent layers, for example, if python-lockfile in different layers,
and there is no python3-lockfile:

$ bitbake python3-lockfile
ERROR: Nothing PROVIDES 'python3-lockfile'. Close matches:
python-lockfile
python-lockfile
python3-aiofiles

Remove the duplicated ones to fix the problem.
