Bug#790382: openjfx: build-dependency on ksh is superfluous

[Markus Koschany]

Source: openjfx
Version: 8u40-b25-1
Severity: normal

Hi,

openjfx is marked for autoremoval from testing because it
build-depends on ksh. I have rebuilt openjfx without ksh and it
appears this build-dependency is not required for building openjfx.
Therefore I think we should remove ksh from Build-Depends.

Regards,

Markus
