libgphoto2: Fix build when security flags are enabled with clang

clang is more pedantic and throws below errors

../../libgphoto2-2.5.8/camlibs/ptp2/chdk.c:1131:14: error: format string is not a string literal (potentially insecure) [-Werror,-Wformat-security]
        sprintf(lua,luascript); /* This expands the %q inside the string too ... do not optimize away. */
                    ^~~~~~~~~

Backport a patch to silence the warnings where it avoids
the use of sprintf all the way
