RFR: JDK-8284758: [linux] improve print_container_info

[Matthias Baesken]

Currently on Linux, os::Linux::print_container_info might print rather badly unreadable memory infos like :

memory_usage_in_bytes: 18029760512
memory_max_usage_in_bytes: 423686144

This could be improved , at a lot of places in the hs_err file output we already print the larger memory-related infos in k , for example rlimit information
or /proc/meminfo.
