news/libcanlock: Update to 3.3.1

pkgsrc patch removed.

3.3.1      2024-05-11
           Bugfix: Add path "$PREFIX/include" to pkg-config files. The
            former "$PREFIX/include/libcanlock-3" is still present for
            compatibility to existing code. The "libcanlock-3" directory
            should be part of preprocessor directives (as documented)
           Bugfix: Replace license name "MIT-like" with \ 
"ICU". Note that
            the license terms are unchanged (only the name was fixed)
           Add machine readable SPDX license identifiers.
