card-piv.c - define USE_SM_NIST and USE_PIV_SM

config.h is included more then once, as it does not have the normal
 "#ifndef _SC_file_H", "#define _SC_file_H" as other header files.

Multiple build combinations are supported:
	- Without any PIV SM
	- With SM  contained in card-piv.c
	- With SM in sm-nist.c,  useable by other card drivers
	- Without OpenSSL is a forth, but not very useful for PIV.
it was nessesary to set different defines and not try
and "#undef" any defines from config.h

The sm-nist is experimental.
