bios_setting: Add a read handler

Tested:
```
~# echo -n "01234567" > /run/oem_bios_setting
~# ipmitool raw 0x2e 0x32 0x79 0x2b 0x00 0x18
 79 2b 00 18 08 30 31 32 33 34 35 36 37
~# rm /run/oem_bios_setting
~# ipmitool raw 0x2e 0x32 0x79 0x2b 0x00 0x18
Unable to send RAW command (channel=0x0 netfn=0x2e lun=0x0 cmd=0x32 rsp=0xca): Cannot return number of requested data bytes
```
