Ever since upstream commit 01dd6da ("Rework the entire API"), first
introduced as part of release v3.0.0, openssl is a hard requirement for
building libjwt. As such, "-DWITH_OPENSSL=ON" also has become a no-op.
In Buildroot, this has been masked somewhat by the implicit select when
gnutls is disabled, but a failure can be reproduced using test-pkg with
a config like:
BR2_PACKAGE_GNUTLS=y
BR2_PACKAGE_LIBJWT=y
Fix this by requiring openssl. Furthermore, building against libressl
does not work because libjwt requires API surface that is not present
there[1], so we need to force libopenssl.
