Unhook a bit from Conscrypt's implementation

Conscrypt's TrustManagerImpl is changing from X509TrustManager to
X509ExtendedTrustManager. apache-http is linking against an SDK
release version without X509ExtendedTrustManager which causes errors.

Remove the instanceof check to since it will work fine without it on the
old and the new code.
