Do not report ReferenceCountedOpenSslClientContext$ExtendedTrustManagerVerifyCallback.verify as blocking call (#10387)

Motivation:

When BlockHound is installed,
ReferenceCountedOpenSslClientContext$ExtendedTrustManagerVerifyCallback.verify
is reported as blocking call.

Modifications:

Add allowBlockingCallsInside configuration for
ReferenceCountedOpenSslClientContext$ExtendedTrustManagerVerifyCallback.verify

Result:

Fixes #10384
