qga/commands: Include proper Solaris header for getloadavg()

Browse Source 
Solaris declares getloadavg() in <sys/loadavg.h>:

    getloadavg(3C)       Standard C Library Functions       getloadavg(3C)

    NAME
           getloadavg - get system load averages

    SYNOPSIS
           #include <sys/loadavg.h>

           int getloadavg(double loadavg[], int nelem);

    [...]

    Oracle Solaris 11.4           23 Jul 2020               getloadavg(3C)

Include it in order to avoid:
