utils: make html version of apparmor.vim manpage

Bug: https://bugs.launchpad.net/bugs/1366572

In the move of the apparmor.vim manpage source from the parser
directory to utils/vim/, the creation of the html version of the
manpage was lost.  This patch fixes that, as well as fixes the vim
Makefile to use the common/Make.rules _clean target (which clears the
pod2htm*.tmp files created by pod2html as well).

It also fixes a bug in common/Make.rules where the _clean target
would report an error when used in a directory where the Makefile
doesn't set the NAME variable, such as utils/vim/.
