Add a recipe for the catch2 testing framework. There's a bug upstream
which makes it impossible to build with gcc7 so include a patch.

+Subject: [PATCH] Fix convert from char on ARM build
+
+Some platforms set the signedness of char to unsigned (eg. ARM).
+Convert from char should not assume the signedness of char.
+
+Fix build issue with -Werror,-Wtautological-unsigned-zero-compare flags.
