Keep gimp-console in the flatpak.

[Jehan]

Apparently some people want to use GIMP headless from the flatpak. Using gimp-console could be the easiest way then.

Note: I hadn't merged this because apparently gimp-console doesn't work properly (cf. the forum link above; I haven't tested myself) so I will want to check this first. No need to change the flatpak if the binary is broken from the start.

@Jehan It's not my intention to sound provocative but, since we aren't sure that gimp-console works, could you know why it is actually included in the nightly manifest?

My previous comment is completely wrong. Ignore it.
