vfs: use 'vfs' module directly in 'mercurial.unionrepo'

" Place this file in ~/.vim/syntax/ and add the following line to your
" ~/.vimrc to enable:
" au BufNewFile,BufRead *.t set filetype=hgtest
"
" If you want folding you'll need the following line as well:
" let hgtest_fold=1
"
" You might also want to set the starting foldlevel for hgtest files:
" autocmd Syntax hgtest setlocal foldlevel=1
