[PATCH] top: parse /proc/meminfo differently, save 114 bytes

[gotrunks at gmail.com]

Hi,

This patch makes top parse /proc/meminfo differently, reducing the
code only used in old kernels (<2.6). Should not break compatibility
(Linux 2.2 and 2.4 tested).

$ make bloatcheck
function                                             old     new   delta
.rodata                                           148282  148253     -29
display_header                                      1065     980     -85
