qtwebkit: fixing build / reducing build log size
GCC 8 introduced a new type of warning `-Wclass-memaccess` which is included in `-Wall`. This warnings spits out *a million* of warnings like the following: ``` [...] /build/source/Source/WTF/wtf/Vector.h:128:15: warning: 'void* memcpy(void*, const void*, size_t)' writing to an object of type 'class WTF::RefPtr<WebCore::TransformOperation>' with no trivial copy-assignment; use copy-assignment or copy-initialization instead [-Wclass-memaccess] memcpy(dst, src, reinterpret_cast<const char*>(srcEnd) - reinterpret_cast<const char*>(src)); [...] `` Logs demonstrating the issue: https://hydra.nixos.org/build/100205478/nixlog/1 While I don't think disabling warnings is the best way to deal with this, there is alrady precedent for this package and I don't feel confident enough to either patch or bump this package. Please view this as a low-friction sub-optimal suggestion in case nobody else has a better fix.
