Peter Simons 3d4068b11a graphviz: patch broken cdt.h header file
The cdt.h header duplicates the signatures of standard library functions
memcmp() and strcpy(), but those signatures don't match the real thing when
building with a C++ compiler, because they lack the no-throw declaration glibc
has. Simply dropping those redundant prototypes remedies the issue.
