The glibc netinet/in.h header in the test container does not have
IPPROTO_MPTCP definition. It is included first through netinet/ip.h and
then __UAPI_DEF_IN_IPPROTO is set in linux/libc-compat.h -- so no
definition comes from include/uapi/linux/in.h either.

I'll send an ifndef/define/endif IPPROTO_MPTCP patch to netdev once it's
build tested. Thank you for the report.
