    Remove unnecessary autoconf check for pkexec --disable-internal-agent option (#776437)
    
    The pkexec --disable-internal-agent option was introduced by this commit
    [1] in polkit 0.98 [2] which is before the minimum 0.102 version needed
    to run X11 apps.  Therefore the option will always be available.  Remove
    the unnecessary check.
