KERNEL PANIC from bad arg to localTimerService from REPL

[dckc]

Describe the bug

From the REPL, if I provide a number where the localTimerService is expecting a bigint, the kernel panics... presumably because the timer device throws a TypeError and the kernel considers this fatal.

To Reproduce

1. Start a REPL
2. Enter E(home.localTimerService).setWakeup(3, handler)
3. kerflewey: 2021-09-17T18:50:36.864Z SwingSet: kernel: ##### KERNEL PANIC: error during syscall/device.invoke: TypeError: (a number) must be a bigint #####

Expected behavior

a user-level error, i.e. a rejected promise in the REPL
