tests: Cope with broken Libgcrypt versions 

* common/t-sexputil.c (test_ecc_uncompress): Ignore unknwon curve
errors.
--

For unknown reasons some versions of Fedora or RHEL provide a patched
version of Libgcrypt with Brainpool support removed.  We better ignore
this error because it is a regression in 2.2.28 although that older
versions could not used Brainpool keys.
