UTIL: Add function sss_parse_name_const

Variable with type 'const char *' can be used as output argument in function
sss_parse_name, but there will be warning.

warning: passing 'const char **' to parameter of type 'char **'
         discards qualifiers in nested pointer types
         [-Wincompatible-pointer-types-discards-qualifiers]
