Trivial fix for epiphany.pc.in

[Maciej Katafiasz <mathrick gmail com>]

Hi,

the one-liner below appears necessary to fix building of recent checkouts 
of epiphany-extensions-webkit. I'm not sure why exactly it didn't surface 
before, but I'm guessing it's the recent de-abstractifying surgery that 
made public headers depend on webkit directly. Thus the most 
straightforward way to fix it is to just list webkit-1.0 as our hard dep, 
and that's exactly what the patch does. If my reasoning is correct and 
there are no objections, I will commit it.

Cheers,
Maciej
