CHOP-753: Report Linux memory stats 1/line, like other platforms. Previous code deliberately flowed the different lines from MEMINFO_FILE together on a single line, which seems pointless to me, since we want to be able to grep the viewer log to recognize individual stats. Also replace classic-C LLFILE* machinery used to read MEMINFO_FILE with std::ifstream and std::getline().
