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
