bitbake.conf: Adds ipv6 to DISTRO_FEATURES_NATIVE
Before we introduced DISTRO_FEATURES_NATIVE on commit:
db1f1adace58763c35774e3fdfeaac5c3ca646fd
ipv6 was enabled by default on DISTRO_FEATURES via DISTRO_FEATURES_LIBC
hence for example python-native was built with ipv6 support.
After this, ipv6 was automatically disabled on DISTRO_FEATURES.
On some packages (python) this may cause errors when they try to download
something on their do_compile stage.
This patch adds ipv6 to DISTRO_FEATURES_NATIVE leaving it as it was
before, to avoid errors like the one mentioned above
