Zhouyi Zhou ae7b1443f4 tools/nolibc: make time_t robust if __kernel_old_time_t is missing in host headers 
[ Upstream commit 0ff52df6b3 ]

Commit d5094bcb5b ("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
94c467ddb2 ("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)
