SBB: man: give the table of contents its own section header.

The `.. contents::` restructuredtext directive seems to produce a level
header that is one level lower than we want it to be. It is not trivial to
change the header level output by rst; instead, this commit adds a section
header of the appropriate level just above the table of contents.
