Old hashed filenames deprecated by IGTF

[vokac]

As announced in the IGTF 1.140 README SSLeay and OpenSSL 0.x series subject name subject name hashes based on MD5 were officially deprecated with a plan to remove them after August 2026. Right now voms-proxy-init still initialize CaNL-java validation without explicit request to use SHA1 hashes

Lines 276 to 280 in 40a877c

	certChainValidator = builder.trustAnchorsDir(trustAnchorsDir)
	.storeUpdateListener(storeUpdateListener)
	.lazyAnchorsLoading(true)
	.validationErrorListener(certChainValidationErrorListener)
	.build();

while e.g. dCache now explicitly specify OpensslHashFunction.SHA1
