[ Upstream commit 6457595db9870298ee30b6d75287b8548e33fe19 ]
In rare cases, when the test environment is very slow, some userspace
tests can fail because some expected events have not been seen.
Because the tests are expecting a long on-going connection, and they are
not waiting for the end of the transfer, it is fine to make the
connection longer. This connection will be killed at the end, after the
verifications, so making it longer doesn't change anything, apart from
avoid it to end before the end of the verifications
To play it safe, all endpoints tests not waiting for the end of the
transfer are now sharing a longer file (128KB) at slow speed.

[ Conflicts in mptcp_join.sh because commit 0c93af1f8907 ("selftests:
mptcp: drop test_linkfail parameter") is not in this version. It moved
the 4th parameter to an env var. To fix the conflicts, the new value
simply needs to be added as the 4th argument instead of an env var. ]
