If a timer overruns too many times before a call to timer_getoverrun the overrun count can overflow and go negative. POSIX.1-2001 specification of timer_getoverrun() supports constant DELAYTIMER_MAX which prevents overflow and caps overrun count. Adds delaytimer_max value, caps overrun count, and exposes value to userland via /proc/sys/kernel/delaytimer_max.
Resolves https://bugzilla.kernel.org/show_bug.cgi?id=12665 - POSIX timers API does not support DELAYTIMER_MAX
