Updated xfig packages fix security vulnerability

A potential buffer overflow exists in the file src/w_help.c at line 55. Specifically, the length of the string returned by getenv("LANG") may become very long and cause a buffer overflow while executing the sprintf() function. This vulnerability could potentially allow an attacker to execute arbitrary code or cause a denial-of-service condition. (CVE-2021-40241)
