ipv[46]: remove @may_fail again, lower the number of routes
We encounter two bugs in CI:
- in NM < 1.43.6: https://bugzilla.redhat.com/show_bug.cgi?id=1861527
- in iproute == 6.1: https://bugzilla.redhat.com/show_bug.cgi?id=2183967
There's another limitation in NM somewhere past 500k v6 routes. Additionally, we encounter performance drops when netns and/or device names and indices get reused. This MR now settles on:
- 2M v4 routes, 500k v6 ones
- skipper for
ip== 6.1.* Bug 1861527 does not need further handling as it appeared only randomly.
