libidn2 2.2.0+ parses Punycode more strictly than older versions and
thus "dig +idnin +noidnout xn--19g" fails with libidn2 2.2.0+ but
succeeds with older versions.
We could preserve the old behavior by using the IDN2_NO_ALABEL_ROUNDTRIP
flag available in libidn2 2.2.0+, but:
- this change in behavior is considered a libidn2 bug fix [1],
- we want to make sure dig behaves as expected, not libidn2,
- implementing that would require additional configure.ac cruft.
Removing the problematic check appears to be the simplest solution as it
does not prevent the relevant block of checks in the "idna" system test
from achieving its purpose, i.e. ensuring dig properly handles invalid
U-labels.
