python3-pyyaml: add 4.2b2

5.1.2 (which is now in meta-oe) is not really recommended by upstream
due incompatibilities caused by the release, which are supposed to be
fixed in 5.2, but which is pending to be released.

+DESCRIPTION = "\
+  YAML is a data serialization format designed for human readability \
+  and interaction with scripting languages.  PyYAML is a YAML parser \
+  and emitter for Python. \
+  .       \
+  PyYAML features a complete YAML 1.1 parser, Unicode support, pickle \
+  support, capable extension API, and sensible error messages.  PyYAML \
+  supports standard YAML tags and provides Python-specific tags that \
+  allow to represent an arbitrary Python object. \
+  .       \
+  PyYAML is applicable for a broad range of tasks from complex \
+  configuration files to object serialization and persistance. \
