- remove any 'permission checks' via geteuid() - with upcoming
security models these might not match the model any more
- this also fixes a bug where ntp_adjtime() was denied (EPERM)
even though only a legit read status was performed
further deprecate struct timezone usage by changing `tzp' argument to
gettimeofday() to void *; align utimes(2) declaration by changing `times`
argument from struct timeval * to struct timeval[2]. From Murray
Armfield in PR standards/25331.
In due curse, reflect these changes in futimes(2), lutimes(2), and
settimeofday(2).
