selftests: mptcp: connect: also cover alt modes

commit 37848a456fc38c191aedfe41f662cc24db8c23d9 upstream.

The "mmap" and "sendfile" alternate modes for mptcp_connect.sh/.c are
available from the beginning, but only tested when mptcp_connect.sh is
manually launched with "-m mmap" or "-m sendfile", not via the
kselftests helpers.

The MPTCP CI was manually running "mptcp_connect.sh -m mmap", but not
"-m sendfile". Plus other CIs, especially the ones validating the stable
releases, were not validating these alternate modes.

To make sure these modes are validated by these CIs, add two new test
programs executing mptcp_connect.sh with the alternate modes.
