apple/Throw: add missing <cstring> header

strlen() and strcpy() are provided by the <string.h> and <cstring> headers (as functions in global and std namespaces, respectively). Compilers MAY provide an implementation for either of the functions without including the extra header but the existence of a declaration without the header is not assured.
