PR #1433: Fix incorrect timespec definition on 32-bit platforms with 64-bit time_t

Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1433

Some 32-bit configurations may use 64-bit time_t, which leads to different layout of userspace timespec and the one expected by SYS_futex implementation in kernel. In particular the issue occurs when using musl libc which has switched to unconditional 64-bit time_t definition.

This patch introduces custom struct timespec with two longs when old SYS_futex is used to match the kernel timespec definition.

Merging this change closes #1433
