Update catch2 testing framework: v1.12.2 -> v2.13.3

We can now use the latest upstream stable version since we bumped up our
minimum C++ standard version.

	* tests/lib/catch.hpp: update to v2.13.3
	* tests/test-symtab.cc (TEST_CASE("Symtab::SimpleSymtabs")): Use
	the corpus variable to avoid unused variable warnings.
