Original GitHub issue: https://github.com/netbirdio/netbird/issues/872

if i run netbird on a homeassistant inside a container and netbird try to set a remote route if got this error in log:

2023-05-18T14:11:18+02:00 ERRO client/internal/engine.go:612: failed to update routes, err: open /proc/sys/net/ipv4/ip_forward: read-only file system

even if the /proc/sys/net/ipv4/ip_forward already 1.

so imho in systemops_linux.go the enableIPForwarding first have to check whether it's already 1 and only if it's 0 have to try to set to 1. so in this case the /proc filesystem shouldn't have to be writeable in the network namespace. it'd be a very simple fix.
