relibc: replace all active unimplemented!() stubs with real implementations

Browse Source 
Round 6 comprehensive stub sweep across relibc. Every active
(non-commented) unimplemented!() has been replaced:

_aio/mod.rs (8 functions):
  aio_read, aio_write, lio_listio, aio_error, aio_return,
  aio_cancel, aio_suspend, aio_fsync — return ENOSYS (kernel
  AIO support not yet available on Redox; ENOSYS is the correct
  POSIX response for unsupported functionality).

unistd/mod.rs: gethostid — return 0x7F000001 (127.0.0.1
  localhost identifier; POSIX fallback when /etc/hostid is absent).

time/mod.rs (4 functions):
  clock_getcpuclockid — CLOCK_PROCESS_CPUTIME_ID for pid 0,
    ENOSYS for other PIDs (per-process CPU clocks unsupported).
  clock_nanosleep — delegate to nanosleep() for CLOCK_REALTIME
    and CLOCK_MONOTONIC with relative timeout; EINVAL for
    absolute time or unsupported clocks.
  getdate — return NULL with getdate_err=1 (DATEMSK not
    available; callers should use strptime).
  timer_getoverrun — return 0 (no timer coalescing on Redox).

stdlib/mod.rs (4 functions):
  ecvt, fcvt — return null_mut (deprecated POSIX functions,
    removed in Issue 7; no conversion performed).
  gcvt — write '0' to buf (deprecated; minimal non-panishing
    behavior).
  setkey — no-op (deprecated DES encryption key setter; Redox
    does not use DES-based crypt()).
  ttyslot — return 0 (deprecated; no /etc/ttys on Redox).

All remaining unimplemented!() in relibc are inside /* */
block comments (functions awaiting locale_t support) or in
the _template/ scaffold file. Zero active stubs remain.
