Remove a version restriction from lipbcap

[silverv]

The < 2.0.0 requirement on version remains for safety reasons. This allows Yukon to specify its own (lower) version of libpcap. Yukon requires an older version because the newer version causes a runtime issue in a built exe file on Windows because of some recursive import of pkg-about.

Here is the error stack trace from Yukon that caused this pull request to happen here:
