cryptolib: put constant arrays in rodata segment

Browse Source 
The SHA256 constants and some algo definitions are currently in the
.data segment, this wastes precious RAM on the EC where read-only data
are stored in flash only.

BUG=chrome-os-partner:12271
TEST=sudo emerge vboot_reference &&
emerge-daisy vboot_reference vboot_reference-firmware chromeos-ec
and manually check the content of the .data segment in the EC binary.
