sleep: Make variable written in signal handler volatile

Browse source 
No difference in practice, but it's tidier and protects us
if we ever use g_interrupted earlier in main -- in that case,
the compiler might chose to keep the variable in a register without
the volatile.

Found by @bugaevc, thanks!
