package/darkhttpd: security bump to version 1.15

Fixes the following security issues:

CVE-2024-23770: Local Leak of Authentication Parameter in Process List

CVE-2024-23771: Basic Auth Timing Attack

https://security.opensuse.org/2024/01/22/darkhttpd-basic-auth-issues.html

Notice that CVE-2024-23770 is only documented as a known weakness, not
fixed.

Also change the license logic to use the dedicated COPYING file available
since 1.14:

https://github.com/emikulic/darkhttpd/commit/a8ae2b1de069588cad23d79a5392445ee9590fcd

This license is ISC, not MIT - So adjust DARKHTTPD_LICENSE to match.
