ulfius: pin the babelouest chain; add orcania and yder; fix directory typo

The ulfius recipe tracked AUTOREV master and could never build: master
requires orcania/yder versions that have no release tags, no recipe for
either existed in any layer, and curl (default-ON WITH_CURL) was
missing from DEPENDS (audit M10). Pin the coherent release set - ulfius
v2.7.15 + orcania v2.3.3 + yder v1.4.20 - add the two new recipes,
add curl, convert to SPDX LGPL-2.1-or-later, and rename the misspelled
recipes-extended/uflius directory.
