fix cgroup_get_value_string problem with *.stat output
the problem was in the low limit for value for the output of stat variables -
now there are used the functions cgroup_read_stats_{begin/next/end} for this
purpose
bogus output:
./src/tools/cgget -r memory.stat /
/:
memory.stat=cache 1024561152
rss 291270656
pgpgin 1209259
pgpgout 888011
inactive_anon 8192
active_anon 2976481
fixed output:
$ ./src/tools/cgget -r memory.stat /
/:
memory.stat=cache 1024610304
rss 291270656
pgpgin 1209271
