sysctl: Move proc_doulongvec_ms_jiffies_minmax to kernel/time/jiffies.c

Browse Source 
Move proc_doulongvec_ms_jiffies_minmax to kernel/time/jiffies.c. Create
a non static wrapper function proc_doulongvec_minmax_conv that
forwards the custom convmul and convdiv argument values to the internal
do_proc_doulongvec_minmax. Remove unused linux/times.h include from
kernel/sysctl.c.
