Wake Liu f44ce7fdbd selftests: timers: Partially revert "Remove local NSEC_PER_SEC and USEC_PER_SEC defines"
This partially reverts commit 80fa614e2f ("selftests: timers: Remove
local NSEC_PER_SEC and USEC_PER_SEC defines").

The original commit removed local definitions of NSEC_PER_SEC and
USEC_PER_SEC in favor of including <include/vdso/time64.h>. However,
NSEC_PER_SEC in vdso/time64.h is defined as 1000000000L, which is
32-bit on 32-bit architectures. This causes integer overflow warnings
in several timer tests when doing arithmetic like NSEC_PER_SEC * 10 on
32-bit systems.

To fix this, restore the local definitions of NSEC_PER_SEC and
USEC_PER_SEC in the test files, but use "LL" suffix consistently
(1000000000LL and 1000000LL) to ensure 64-bit arithmetic and avoid
overflows.

We keep the cleanup from the original commit that renamed plural
definitions (NSECS_PER_SEC/USECS_PER_SEC) to singular ones in
posix_timers.c, but we now define them locally there as well.
This also removes the dependency of the selftests on the internal
kernel header <include/vdso/time64.h>.
