[Rd] feature request for non-sweave vignettes

Currently Makefiles for vignettes are only supported for .tex files.  Could
the tools package be modified to allow file extensions to be specified for
a vignette engine?  Having the pandoc pdf conversion in a Makefile rather
than through R would be tidier in some cases.

If I specify my vignette engine as

  pattern = '\\.[Rr](md|nw)$',
  output = c('md', 'tex'),

the `tools:::find_vignette_product` function could have

`if (final) c("pdf", "html") else unique(c("pdf", "html", "tex",

that's probably the only line that would need changing.
