[SRU][Focal][PATCH 1/1] UBUNTU: SAUCE: selftests/net: skipping tests for older ip command releases

[Jose Ogando]

BugLink: https://bugs.launchpad.net/bugs/1990800

When running fib_nexthop_nongw from V5.4 on older releases (i.e.
Bionic) the nexthop ip subcommand is not available.
This patch queries ip capabilities beforehand, and will execute
or skip where aplicable.
