Root user cannot decode SMBIOS tables from local file

[honggli]

If I run dmidecode command as root user to decode SMBIOS tables from raw data I dump before, it failed.

./dmidecode --from-dump ~/dmidecode.bin
# dmidecode 3.5
Reading SMBIOS/DMI data from file /root/dmidecode.bin.
Can't read memory from /root/dmidecode.bin

It seemed root user could use /dev/mem only, while non-root user could decode SMBIOS tables from local file.
This restriction seems not necessary, especially for some systems we only have root user.

This was fixed in version 3.6. It doesn't seem like it will be backported to version 3.5 considering the change occurred 1.5 years ago.
