(maint) Remove needless check in setting default

This line is not sane for the setting of the log_level default

   loglevel = %x{ #{puppet_path} config --section agent --log_level notice print log_level }.chomp

this sets log_level to notice, and then return the output of the log_level setting

      loglevel = "notice"

is the same thing with fewer steps
