Ranph, I confirm: in Ubuntu 18.04 and 16.04 the path to Symbol font in /devpdf/download is wrong. The path fix indeed results in embedding all fonts in case of compilation as
groff -Tpdf -P-e ... Now the question, what if we compile with pdfroff ...? It does not support -e option and does not embed Symbol into PDF. Since pdfroff is devps-based and internally must be using the ps2pdf, it may be a matter of inernal tuning of ps2pdf command to make it embed all fonts.
