Log descriptor-download bootstrapping messages less verbosely

This is a fix for 9963.  I say this is a feature, but if it's a
bugfix, it's a bugfix on 0.2.4.18-rc.

Old behavior:

    Mar 27 11:02:19.000 [notice] Bootstrapped 50%: Loading relay descriptors.
    Mar 27 11:02:20.000 [notice] Bootstrapped 51%: Loading relay descriptors.
    Mar 27 11:02:20.000 [notice] Bootstrapped 52%: Loading relay descriptors.
    ... [Many lines omitted] ...
    Mar 27 11:02:29.000 [notice] Bootstrapped 78%: Loading relay descriptors.
    Mar 27 11:02:33.000 [notice] We now have enough directory information to build circuits.

o Minor features:
- Don't log so many notice-level bootstrapping messages at startup about
downloading descriptors. Previously, we'd log a notice whenever we
learned about more routers. Now, we only log a notice at every 5% of
progress. Fixes bug 9963.
