Change BKS KeyStore to use default provider for crypto.

The default implementation of the BKS KeyStore always requests the Bouncy
Castle implementation of JCA algorithms, which will fail when those
algorithms are deprecated.  Have it use the default provider instead, which
will result in it using Conscrypt versions instead when available.
