Fix wkhtmltopdf bugs

The wkhtmltopdf library does not work with the latest version of alpine. To
workaround this, a known working image based on an older alpine image is pulled
in and relevant libraries copied to the target image.

The `snappy` package required a few updates to support this, including setting
the wkhtmltopdf binary path explicitly and to enable access to local files
(disabled by default).
