Tweaks and unification of init wrappers

Added parameter for the new `--reconnect-interval`.

Clean out .pyc's on startup in both .rpm and .deb wrappers.  If a package deploys .py's for lib/ or etc/ with older timestamps than the last tcollector startup the .pyc's get used instead, which is confusing.

Don't strip hostnames (the Debian init script doesn't) and add some startup runlevels to the .rpm wrapper.
