Fix PhantomJS ssl error

[fluix-dev]

PhantomJS has had an error for the past while (direct issue here, but mentioned in 2018 here) where certain system configurations (Debian) would cause the following error on pdf generation:

Auto configuration failed
140098268257920:error:25066067:DSO support routines:DLFCN_LOAD:could not load the shared library:dso_dlfcn.c:185:filename(libssl_conf.so): libssl_conf.so: cannot open shared object file: No such file or directory
140098268257920:error:25070067:DSO support routines:DSO_load:could not load the shared library:dso_lib.c:244:
140098268257920:error:0E07506E:configuration file routines:MODULE_LOAD_DSO:error loading dso:conf_mod.c:285:module=ssl_conf, path=ssl_conf
140098268257920:error:0E076071:configuration file routines:MODULE_RUN:unknown module name:conf_mod.c:222:module=ssl_conf

The solution to this is to assign an environment variable OPENSSL_CONF to /etc/ssl/. Some systems are unaffected by the issue and won't be affected by this fix.

Sure, I'll merge this, though note that PhantomJS is dead and you should probably be using the Slimer backend instead :)

Note that SlimerJS is dead and you should probably use the puppeteer backend.

Yes, that.
