Subject: selftests/bpf: make fexit_stress test run in serial mode
Patch-mainline: v5.19-rc1
Git-commit: 5790a2fee02c48e28fde2ce7ea4765eeadcda0ba
References: jsc#PED-1377
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.
