Add isFinite flag to OpenSSLBIOInputStream.

The BIO created by OpenSSLBIOInputStream currently returns -1 and sets
the retry flag when read() returns zero on the underlying InputStream.
This is correct for “infinite” streams (like a socket), but isn't
correct for streams that have a definitive EOF.

This change adds a flag to OpenSSLBIOInputStream so that cases where the
input is finite (i.e. when parsing a PKCS#7 or X.509 block) can
correctly return 0 at EOF from |BIO_read|.
