Adds proc files /proc/uid_cputime/show_uid_stat and
/proc/uid_cputime/remove_uid_range.
show_uid_stat lists the total utime and stime for the active as well as
terminated processes for each of the uids.
Writing a range of uids to remove_uid_range will delete the accounting
for all the uids within that range.

[AmitP: Refactored the original patch because upstream commit
605dc2b31a ("tsacct: Convert obsolete cputime type to nsecs")
made cputime_t type obsolete, so use u64 nanoseconds directly instead.
Also folded following android-4.9 changes into this patch
48a9906c0fd8 ("ANDROID: proc: uid_cputime: create uids from kuids")
453ac31cab34 ("ANDROID: proc: uid_cputime: fix show_uid_stat permission")]
