Add CLOCK_BOOTTIME as a CLOCK_MONOTONIC alias
Makes CLOCK_BOOTTIME available with * clock_gettime * timerfd_create * clock_gettime vDSO CLOCK_BOOTTIME is implemented as an alias to CLOCK_MONOTONIC. CLOCK_MONOTONIC already keeps track of time across save and restore. This is the closest possible behavior to Linux CLOCK_BOOTIME, as there is no concept of suspend/resume. Updates google/gvisor#218
