mpm: periph manager: Fix get_mb_eeprom() return value formatting

The get_mb_eeprom() RPC call is supposed to return a string -> string
map and thus converts all EEPROM entries to strings. However, for raw
strings, the existing conversion (using str()) was not correct (we need
to decode raw strings first).

This would lead to things like the serial being returned as b'ABCD123'
instead of just ABCD123.
