tools/cgsnapshot: fix string null terminate in parse_controllers()

Fix string not null terminated warning, reported by the Coverity tool:

CID 258299 (#2 of 2): String not null terminated (STRING_NULL)18.
string_null: Passing unterminated string *controllers to
display_controller_data, which expects a null-terminated string.

use snprintf() instead of strncpy() and manually terminate the string to
keep Coverity happy.
