check_load: add alternative uptime syntax

Browse source 
check_load parses load from the uptime command if no proc filesystem is available. Seems
like there are at least 2 different uptime outputs.

linux:
 20:44:34 up 25 days,  2:07, 13 users,  load average: 0.13, 0.17, 0.22

freebsd 8:
 8:44PM  up  4:29, 1 user, load averages: 0.00, 0.00, 0.00
