emulators/i386-wine: Make dependency on wine-gecko generic

Similar to commits dc73fd607fb79017cf74182613659ac9c4340bdd and
18fcc610bf93b40517bdb3f3ba945659a70cb6d0 solving this for wine-mono,
the dependency on wine-gecko had the actual version number hardcoded,
which is easy to miss and a maintenance burden.

Simply depend on the port instead for wine-gecko as well.
