perf test: Fix 'perf test BPF' when it fails to find a suitable vmlinux
Two bugs in 'perf test BPF' are found when testing BPF prologue without
vmlinux:
# mv /lib/modules/4.3.0-rc4+/build/vmlinux{,.bak}
# ./perf test BPF
37: Test BPF filter :Failed to find the path for kernel: No such file or directory
Ok
Test BPF should fail in this case.
After this patch:
# ./perf test BPF
37: Test BPF filter :Failed to find the path for kernel: No such file or directory
FAILED!
# mv /lib/modules/4.3.0-rc4+/build/vmlinux{.bak,}
# ./perf test BPF
37: Test BPF filter : Ok
