import-checker: allow relative import a module being checked
This would make the checker more friendly for 3rd-party code. For example,
In remotefilelog/x.py, it may have:
from . import shallowutils
That could trigger "relative import of stdlib module" if
"remotefilelog" was installed in the system. If the module being checked
conflicts with the system module, it makes sense to not treat that module as
system module. This patch makes it so.
