[krbdev.mit.edu #7155] default_tgs_enctypes not used for client TGS enctypes

[Greg Hudson via RT]

Through 1.6, the client uses default_tkt_enctypes for AS requests and 
default_tgs_enctypes for TGS requests.  But in r21879, when we converted 
the code to use KRB5_CONF macros for profile variable names, we made a 
typo in krb5_get_tgs_ktypes:

-       return(get_profile_etype_list(context, ktypes, 
"default_tgs_enctypes",
+       return(get_profile_etype_list(context, ktypes, 
KRB5_CONF_DEFAULT_TKT_ENCTYPES,

As a result, since 1.7 we have been using default_tkt_enctypes for TGS 
requests.
