[ Upstream commit 0ff52df6b32a6b04a7c9dfe3d7a387aff215b482 ]
Commit d5094bcb5bfd ("tools/nolibc: define time_t in terms of __kernel_old_time_t") made nolibc use the kernel's time type so that `time_t` matches `timespec::tv_sec` on all ABIs (notably x32).
But since __kernel_old_time_t is fairly new, notably from 2020 in commit 94c467ddb273 ("y2038: add __kernel_old_timespec and __kernel_old_time_t"), nolibc builds that rely on host headers may fail.
Switch to __kernel_time_t, which is the same as __kernel_old_time_t and has existed for longer.
Tested in PPC VM of Open Source Lab of Oregon State University (./tools/testing/selftests/rcutorture/bin/mkinitrd.sh)
