etc: remove leftover leading empty comments, blank lines

[• karels]

Summary

Remove leftover empty leading comments/blank lines that had been
spacers between $FreeBSD$ and the following content in config files
in src/etc.

[imp]

I'm not sure all of these should go... lemme check history first

[imp]

Not sure about the specific ones I flagged, mostly because of trailing '#' lines.
These comments weren't in 4.4BSD and when FreeBDS added comments,
we went from a single # $Id:$ line to that, a blank # line, the comment and
a trailing # line. Weak surmise is that the leading and trailing # were intended.
But I'm not that excited either way.

The rest are fine, no question.

I think this one should stay given the trailing #

Does that include mtree/Makefile and mtree/README? Both had leading blank lines.

No. Those look like they should be removed imho.
