man: add various filenames to the index

Everything which is an absolute filename marked with <filename></filename>
lands in the index, unless noindex= attribute is present. Should make
it easier for people to find stuff when they are looking at a file on
disk.

Various formatting errors in manpages are fixed, kernel-install(1) is
restored to formatting sanity.
