selftests: timers: Remove local NSEC_PER_SEC and USEC_PER_SEC defines

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.

selftests: timers: ksft_exit functions do not return

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.

selftests/timers: Add missing fflush(stdout) calls

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.
