selftests: openvswitch: don't hardcode the drop reason subsys
WiFi removed one of their subsys entries from drop reasons, in
commit 286e69677065 ("wifi: mac80211: Drop cooked monitor support")
SKB_DROP_REASON_SUBSYS_OPENVSWITCH is now 2 not 3.
The drop reasons are not uAPI, read the correct value
from debug info.
We need to enable vmlinux BTF, otherwise pahole needs
a few GB of memory to decode the enum name.
