ddb: safely copy symbol names into the symtab structure

Use strncpy instead of strcpy to copy the name of a symbol into the
symtab structure.  Make sure that the string is properly terminated.

Found using Coverity.

* ddb/db_sym.c (db_add_symbol_table): Use strncpy instead of strcpy,
ensure string termination.
