   servers: fix to reverse `SA_RESTART` option for `sigaction()` on modern codepath
   Historically servers used the deprecated `siginterrupt()` function to
   configure restart behavior on specific signals. It accepts a flag, where
   1 means to remove the `SA_RESTART` option, and 0 means to enable it.
   
   In year 2021 3fb6e5a01001b8c7dfdc33a89041178aac381a27 introduced the
   modern alternative to the codebase, replacing `siginterrupt()` with
   `sigaction()`. After this patch, supporting, modern, systems reacted on
   the same flag, but, by accident, set the `SA_RESTART` bit when flag is
   1, and did not set it when 0. This reversed the previous behavior, and
   the one still used on the `siginterrupt()` legacy codepath.
   
   Fix it by revesring the `SA_RESTART` logic for the `sigaction()`
   codepath, syncing it with the pre-existing behavior.
   
   I find it odd this did not cause any perceivable issue for 5 years, even
   though it's the active one in most Unix envs.
   
   Spotted by GitHub Code Quality, though suggesting to fix
   `siginterrupt()` calls. But looking into the history, those were correct
   all along.
