vppinfra: remove unused historical code

"timer.[ch]" used a signal handler to deliver timer callbacks. Without
indulging in a set of sigprocmask(...) system calls, it would be
unsafe to use the mechanism.

Rather than wait for another developer to accidentally open this
particular can of worms, best to remove the code. It's nothing more
than an attractive nuisance at this point.
