[nft PATCH] tests: shell: Stabilize sets/0043concatenated_ranges_0 test

[Phil Sutter <phil@nwl.cc>]

On a slow system, one of the 'delete element' commands would
occasionally fail. Assuming it can only happen if the 2s timeout passes
"too quickly", work around it by adding elements with a 2m timeout
instead and when wanting to test the element expiry just drop and add
the element again with a short timeout.
