invalid json in 10-weave.conflist

[fvigotti]

weave 2.8.1 create a invalid /etc/cni/net.d/10-weave.conflist it contain "hairpinMode": True which should be hairpinMode": true

and this trigger error in podman json parsing :

ERRO[0000] Error loading CNI config list file /etc/cni/net.d/10-weave.conflist: error parsing configuration list: invalid character 'T' looking for beginning of value 

do note that other values correctly write : true instead of :True , ie : ` "capabilities": {"portMappings": true}, "snat": true
