Matthieu Baerts d328fe8706 selftests: mptcp: join: avoid using 'cmp --bytes'
BusyBox's 'cmp' command doesn't support the '--bytes' parameter.

Some CIs -- i.e. LKFT -- use BusyBox and have the mptcp_join.sh test
failing [1] because their 'cmp' command doesn't support this '--bytes'
option:

    cmp: unrecognized option '--bytes=1024'
    BusyBox v1.35.0 () multi-call binary.

    Usage: cmp [-ls] [-n NUM] FILE1 [FILE2]

Instead, 'head --bytes' can be used as this option is supported by
BusyBox. A temporary file is needed for this operation.

Because it is apparently quite common to use BusyBox, it is certainly
better to backport this fix to impacted kernels.
