posix_other: add define to force time_t to 64 bit [backport] (#14753)

Browse source 
This is a temporary remedy for time_t transition to 64 bit on newer
Linux libc (musl >= 1.2.0, glibc >= 2.32).

In the future we might want to move away from libc, or figure out a way
to reliably detect the real size of C types at compile time, both of
which are difficult.
