parallel threads when building webkit

[Thiago Milczarek Sayão]

Johan,

I often have to try to build it a few times before it succeeds (on Linux).
And I used an old Ryzen 7 1700X with 16 threads, 16GB. I have now upgraded
it, but I haven't built webkit yet. I'm really scared of it :)

So limiting the threads seems like a good idea.
