[BFN] Fix exception when fwutil run without sudo (#10335)
* [BFN] Fix for run fwutil without sudo
            SONiC has a concept of "platform components"
            this may include - CPLD, FPGA, BIOS, BMC, etc.

            These changes are needed to read the version of the BIOS and BMC component.

            What I did
                    The previous implementaion of component.py expect fwutil run with sudo.
	       When fwutil run without sudo, there are an exception:
```
Traceback (most recent call last):

```
           How I did it
                    Modification of dmidecode command

           How to verify it
                    Run manually 'fwutil' (without sudo)

	   Previous command output had exception

	   New command output:
		Root privileges are required

How I did it
Modification call of dmidecode command.
Added modification of log files access attributes before file open operations.

How to verify it
Run manually 'fwutil' (without sudo)

New command output have no exception.
