[OE-core] [PATCH] curl: control ipv6 support based on DISTRO feature

[Andre McCurdy]

By default ipv6 is auto detected for native builds but disabled when
cross compiling.

This commit adds a PACKAGECONFIG option, unconditionally enabled for
native and nativesdk builds and controlled by the ipv6 DISTRO feature
for target builds.
