timers tests defines CLOCKIDs locally. Remove all local CLOCKIDs except
CLOCK_HWSPECIFIC and use defines from time.h header file.
CLOCK_HWSPECIFIC and CLOCK_SGI_CYCLE are the same and CLOCK_SGI_CYCLE
is deprecated,

Remove local NSEC_PER_SEC and USEC_PER_SEC defines. Pick them up from
include/vdso/time64.h. This requires -I $(top_srcdir) to the timers
Makefile to include the include/vdso/time64.h.
posix_timers test names the defines NSECS_PER_SEC and USECS_PER_SEC.
Change posix_timers test references to the defines to match the
defines in the header file.

After commit f7d5bcd35d42 ("selftests: kselftest: Mark functions that
unconditionally call exit() as __noreturn"), ksft_exit_...() functions
are marked as __noreturn, which means the return type should not be
'int' but 'void' because they are not returning anything (and never were
since exit() has always been called).
To facilitate updating the return type of these functions, remove
'return' before the calls to ksft_exit_...(), as __noreturn prevents the
compiler from warning that a caller of the ksft_exit functions does not
return a value because the program will terminate upon calling these
functions.

Mixing up argc/argv went unnoticed because they were not used. Still,
this is worth fixing.

When running under a pipe, some timer tests would not report output in
real-time because stdout flushes were missing after printf()s that lacked
a newline. This adds them to restore real-time status output that humans
can enjoy.

There is no need to keep timers tests in sync with external timers
repo. Drop support for !KTEST to support for building and running
timers tests without kselftest framework.

Recently a kernel side NTP bug was fixed via the following commit:
2619d7e9c92d ("time: Fix timekeeping_freqadjust()'s incorrect use of abs() instead of abs64()")
When the bug was reported it was difficult to detect, except by
tweaking the adjtimex tick value, and noticing how quickly the
adjustment took:
https://lkml.org/lkml/2015/9/1/488
Thus this patch introduces a new test which manipulates the
adjtimex tick value and validates that the results are what we
expect.
