selftests: mptcp: add missing kconfig for NF Mangle

commit 2d41f10fa497182df9012d3e95d9cea24eb42e61 upstream.

Since the commit mentioned below, 'mptcp_join' selftests is using
IPTables to add rules to the Mangle table, only in IPv4.

This KConfig is usually enabled by default in many defconfig, but we
recently noticed that some CI were running our selftests without them
enabled.
