commit: https://git.buildroot.net/buildroot/commit/?id=96c3b52132b41716ca445b4c73a1a8886c26e5ee
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

ualpn requires mbedTLS to be configured and built with
MBEDTLS_X509_ALLOW_UNSUPPORTED_CRITICAL_EXTENSION
which is not the default and can be a security risk.

Therefore make BR2_PACKAGE_UACME_UALPN depend on
BR2_PACKAGE_OPENSSL || BR2_PACKAGE_GNUTLS.

Fixes http://autobuild.buildroot.net/results/d241121f8155bad9b6b25c16234576abb7fc940b
