rwsig: Fix mapped read location for rwsig / pubkey
Mapped reads are relative to CONFIG_EC_*_STORAGE_OFF, not CONFIG_R*_MEM_OFF. The previous implementation happened to work for internal mapped storage (eg. stm32) but failed for external mapped storage which is copied to SRAM before execution (eg. npcx). BUG=b:62841029 TEST=Verify sysjump works again on eve/poppy/soraka. Verify sysjump and sig verification continues to work on fizz and stm32.
