posix-clocks: Check write permissions in posix syscalls
pc_clock_settime() and pc_clock_adjtime() do not check whether the fd
was opened in write mode, so a clock can be set with a read only fd.
[ tglx: We deliberately do not return -EPERM as we want this to be
distingushable from the capability based permission check ]
