start: handle kernel header and kernel incompatability

We might e.g. be compiled in a container with old kernel headers. In this
scenario CLONE_PIDFD will work but pidfd_send_signal() might not be detected
because __NR_pidfd_send_signal is not defined because the kernel headers don't
match the kernel version.

This explains and fixes test-suite hangs on Jenkins I've recently debugged.
