Update to linux-raw 0.0.39. (#200)
* Update to linux-raw 0.0.39. This version drops support for multiple Linux API versions, so this drops all the `v5_4::` and `v5_11::` qualifiers. * Implement fallback for old-style socket timeouts. Linux socket timeout options moved from y2038-unsafe `timeval` to y2038-safe `__kernel_timespec`. Optimistically use the new options first, and implement fallback code to use the old versions if needed. * Update to linux-raw-sys 0.0.40, which fixes the riscv64 issues. * Use `__NR_ugetrlimit` on architectures which have it. * Factor convertions to/from `Duration` into helper functions.
