Fix the REALTIME() dialplan function. ast_build_string() advances the string
pointer to the position to begin the next write into the buffer. So, this
pointer can not be used to copy the contents of the string later. The
beginning of the buffer must be saved. Interestingly enough, this code could
not have ever worked. (Pointed out by Sebb on IRC, thanks!)
