libpldm: bios_table: Update attr value table
SetBIOSAttributeCurrentValue will update an attribute
in attribute value table. And in our implementation,
all attributes are stored continuously in the table.
It may be more appropriate to build a new table with the
original table and the attributes to be updated, since
the length of each attribute could be different.
