ntdll: Fix tick count calculation on Mac.
...
Inspired by a patch by Andrew Eikum.
macOS's mach_absolute_time() stops counting when the computer goes to
sleep/suspend/hibernate/etc. However, Windows's GetTickCount() does not
stop counting. mach_continuous_time() matches Windows's behavior.
BSD's CLOCK_MONOTONIC already counts asleep time.
Unfortunately, there is no clock source on Linux which does exactly what
we want. CLOCK_MONOTONIC_RAW is unaffected by NTP adjustment, but like
mach_absolute_time() doesn't keep ticking when the computer is asleep.
CLOCK_BOOTTIME does keep ticking, but it is affected by NTP adjustments.
CLOCK_MONOTONIC has both problems. What's needed is a
CLOCK_BOOTTIME_RAW, which would not be slewed by adjtimex(2) and would
count time spent asleep.
To avoid issues with skew and performance, this patch falls back to
mach_absolute_time() on macOS if mach_continuous_time() is unavailable.
Note that mach_continuous_time() was introduced in macOS 10.12, meaning
that if the minimum version required is less than that, it will be
linked weakly. Therefore we must check that it is nonnull before
attempting to call it.

server: On macOS, don't use clock_gettime() even if it's available.
...
The problem is building against the 10.12 or later SDK but deploying to 10.11
or earlier. Support for clock_gettime() is new with 10.12 so configure finds
it and the code uses it, but the symbol is weak linked and resolves to NULL
when running on earlier versions.
