Move vim/after/ftplugin files into vim/ftplugin

None of the settings in here need to be run after the core configuration
files are loaded, so I'll put them in a slightly more accessible or
logical place.

This adds a new target `install-vim-ftplugin`, and makes that a
prerequisite of the `install-vim` target.
