selftests/bpf: add test for accessing ctx from syscall program type
We need to also export the kfunc set to the syscall program type,
and then add a couple of eBPF programs that are testing those calls.
The first one checks for valid access, and the second one is OK
from a static analysis point of view but fails at run time because
we are trying to access outside of the allocated memory.
