[PATCH net 3/3] selftests: mptcp: sockopt: set EXIT trap earlier

[Matthieu Baerts (NGI0)]

From: Geliang Tang <tanggeliang@xxxxxxxxxx>

Set the EXIT trap for cleanup immediately after creating temporary file
variables, before init and make_file, to ensure cleanup runs on any
failure or interruption during the early setup phase.

Fixes: dc65fe82fb07 ("selftests: mptcp: add packet mark test case")
