    uptime plugin: don't cache boot time and simplify Linux code
    
    Caching boottime on startup yields incorrect uptime values if system
    date changes after the daemon is started.
    This is almost certain to happen on embedded systems without RTC, where
    clock is set from NTP server at some point after boot process.
    
    On Linux, we can retrieve uptime directly by either reading /proc/uptime
    (it's sufficient to read a few bytes) or calling sysinfo() function.
    Use the latter since it's the most efficient way in speed, memory
    requirements and code simplicity terms.
