1. cmake: rework NSS and SSL …

   The cmake build should select NSS or CryptoPP consistently with
   current autoconf logic, as used in our RHEL builds (-DWITH_NSS),
   and the SSL linkage must match (for NSS, -lssl3).
   
   With this change, there is no direct linkage with libssl when NSS
   is selected (I still see indirect linkage via libcurl, in turn
   via libssh2, looking into that).
   
   With guidance from upstream and downstream, NSS builds are now
   selected by default.

2. automake, ssl: real openssl detection, fix ssl linkage w/NSS …

   This change mainly intends to prevent linking with libssl when the
   crypto provider is NSS, which provides an SSL implementation (the
   implementation we must use and prefer when NSS is selected).
   
   Secondarily, actually detect openssl when it is selected, which
   happens by default and co-selects with cryptopp.  To do this, we
   import the ax_check_openssl.m4 from the automake archive.
   
   Since upstream builds now prefer NSS crypto, make this the default.
