Selftests are supposed to run on any kernels, including the old ones not supporting all MPTCP features. One of them is the checks of the default limits returned by the MPTCP in-kernel path-manager. The default values have been modified by commit 72bcbc46a5c3 ("mptcp: increase default max additional subflows to 2"). Instead of comparing with hardcoded values, we can get the default one and compare with them. Note that if we expect to have the latest version, we continue to check the hardcoded values to avoid unexpected behaviour changes.
