Maybe fix Gxlat language translator

Of course we can perform translations online, such as at translate.google.com; however Gxlat is a local GUI app that will use multiple translation engines. It was written in 2010, by forum member vovchik, and I made some small changes in 2018.

I have a report from SteveS that it is not working properly. Gxlat uses the 'trans' CLI utility, which vovchik included in Gxlat, and I see that the PET has the latest version of trans, so I must have updated it. trans is also available in the Devuan repo, as package 'translate-shell', and I see it is the same as that in Gxlat PET.

Looking at the required deps for translate-shell, I see that 'libfribidi-bin' is missing; this has the 'fribidi' utility. We didn't have this problem in Scarthgap, but in Devuan/Debian the DEB packages are split up into many smaller ones.

So, have added libfribidi-bin to the builtin package list, and we shall see if that improves Gxlat.
