selftests: net: add missing required classifier

the udpgro_fraglist self-test uses the BPF classifiers, but the
current net self-test configuration does not include it, causing
CI failures:

 # selftests: net: udpgro_frglist.sh
 # ipv6
 # tcp - over veth touching data
 # -l 4 -6 -D 2001:db8::1 -t rx -4 -t
 # Error: TC classifier not found.
 # We have an error talking to the kernel
 # Error: TC classifier not found.
 # We have an error talking to the kernel

Add the missing knob.
