bug: lib/gnutlsxx.cpp missing various ENABLE_XXX ifdefs

[Bill Randle]

I fixed my previous problem with the missing ifdef in mpi.c (see patch
below). A similar problem also exists in gnutlsxx.cpp where the only
ENABLE_XXX ifdefs are ENABLE_OPENPGP and ENABLE_SRP. There should also
be ifdefs for ENABLE_PKI and ENABLE_PSK (and perhaps others?).

P.S. I apologize if this has been reported already; I did look back
several months in the mailing list archives.
