The original ipsec_from_lxc_test.c covers tunnel=vxlan plus endpointRoutes=disabled only. This commit splits it into generic part (*_generic.h) and configure-specific part (*_tunnel.c). Signed-off-by: Zhichuan Liang <gray.liang@isovalent.com>

Macro ENABLE_ENDPOINT_ROUTES is defined instead of ENABLE_ROUTING. TC_ACT_OK is also expected rather than TC_ACT_REDIRECT. Signed-off-by: Zhichuan Liang <gray.liang@isovalent.com>

Bpf from_network is used to attach on eth0 when tunnel is disabled. This
commit covers tunnel=disabled with endpointRoutes={enabled,disabled}.
