[PATCH] selftests/futex: print tv_sec as long long

[Sasha Levin <sashal@kernel.org>]

On 32-bit architectures with a 64-bit time_t, such as armhf in Debian
13, tv_sec is a long long, and printing it with %ld warns:

  futex_requeue_pi.c:351:30: warning: format specifies type 'long' but the argument has type '__time64_t' (aka 'long long') [-Wformat]

Cast it to long long and print it with %lld.

Found with a 32-bit build of the selftests with a 64-bit time_t (gcc 16
and clang 21 with -m32 -D_TIME_BITS=64 -D_FILE_OFFSET_BITS=64);
KernelCI's 32-bit arm builds show the same warnings. The changed files
build without format warnings there now, and the x86_64 builds don't
change. The other selftests get the same kind of fix in separate
patches.
