[FABG-723] add int tests for dist signatures

	Integration test includes external signing using OpenSSL

	When signing with an external tool like OpenSSL, one must
	convert the signature with a low S value to prevent from
	ECDSA signature malleability. This is a Fabric requirement
	as well. For more details, see the comments about this in the call:
	loadExternalSignature() found in
	test/integration/e2e/orgs/multi_orgs_ch_update_signatures_test.go
