libcheck: disable subunit support

We don't have a recipe for subunit in core (or any layer in the layer
index), and unfortunately a bug in the CMakeLists means that the native
build can detect subunit on the host (so host contamination) and only
half-enable it, so the build fails.

Take a patch from upstream's github to add an option for subunit, and
explicitly disable it.

+Subject: [PATCH] Allow disabling autodetection of subunit library
+
+It can be useful to avoid linking to subunit when we are building the check
+library for the host, e.g. in a buildroot recipe, where the built check is
+linked into other applications which are used on the host to build images.
+
+These applications are built with the host's cross-compiler and can use
+the host's pkgconfig to determine if libraries are available. When check
+is linked against other libraries, it can fail this check for subunit.
+
+Allow disabling the autodetection of subunit with a configure flag
