[patch] fix kernel version parsing when it has more than 3 components

[Mike Frysinger]

with kernel versions having more than 3 components being common place, a bug 
was noticed in _dl_discover_osversion() where it would parse all parts of the 
kernel version rather than just consuming the first 3.  for example, the 
function would return incorrect values when running on "2.6.21.5" but would 
work properly on "2.6.21".  the attached patch fixes this by bailing out 
after processing the first three components.
