configs/turris1x: disable openssl assember optimizations

On Turris 1.x it seems that some assember code is not correct and result
are failures for some domain's certificates such as google.com or
pypi.org.

configs/turris1x/openssl

+# Disable assembler optimization
+# This can be potentially removed later with some future openssl update but
+# connection using TLS1.3 to pypi.org and google.com should be tested.
