fix(windows-agent): Check that IPs are convertible to ipv4

[ashuntu]

If the system receives an IPv6 address, then running the agent with mocks (for example, when running integration tests) can result in panics. This fixes that issue by checking if the IP is convertible to Ipv4.

For context, this came up when I attempted to run the Flutter integration tests on a network and host that technically support IPv6.
