commonlib: update fsp_relocate to make it compatible with UEFI 2.6

UEFI 2.6 spec casts the return of FFS_FILE2_SIZE to a UINT32
    which cannot be read using read_le32(&returnval). Add in a
    cast in order to safeguard for any non x86 architecture that may
    use this relocate. The proper change will be to get the UEFI
    header files changed to not cast this return value.
