Subject: [PATCH 01/12] Include <sys/types.h> in staputil.h for gid_t and
 friends

staputil.h declares get_gid(), in_group_id() and run_unprivileged()
using gid_t, uid_t and pid_t, but it only includes <signal.h>,
<stdint.h>, <spawn.h>, <assert.h> and <poll.h>.

glibc happens to define all three types as a side effect of <signal.h>.
musl does not: its <signal.h> declares pid_t and uid_t but never gid_t,
so every translation unit that includes staputil.h fails with

  staputil.h:100:12: error: 'gid_t' does not name a type

Include <sys/types.h>, which POSIX makes the home of these types.
