[PATCH bpf-next] selftests/bpf: make fexit_stress test run in serial mode

[Andrii Nakryiko]

fexit_stress is attaching maximum allowed amount of fexit programs to
bpf_fentry_test1 kernel function, which is used by a bunch of other
parallel tests, thus pretty frequently interfering with their execution.

Given the test assumes nothing else is attaching to bpf_fentry_test1,
mark it serial.
