Skip the test with test__skip() for systems that do not
support "ip mptcp", so that CI can also pass.

2.43.0

Fix sleep() usage: sleep() takes an integer, not a float/double.

tools/testing/selftests/bpf/prog_tests/mptcp.c:373:9: error: implicit conversion from 'double' to 'unsigned int' changes value from 0.1 to 0 [-Werror,-Wliteral-conversion]
    373 |                 sleep(0.1);
        |                 ~~~~~ ^~~

Use usleep() instead.
