Revert "net/miniupnpd: ext_ip_reserved_ignore support"

This patch is causing several issues [1], which then were reported to
upstream [2] and it was not accepted by upstream [3]. This results that
nobody maintain this custom patch and it is not useful as it is changing
addr_is_reserved behavior.

[1] https://github.com/openwrt/packages/issues/15258
[2] https://github.com/miniupnp/miniupnp/issues/542
[3] https://github.com/miniupnp/miniupnp/pull/511

This reverts commit b76aa99194.
