fix(ovsm): Ensure .dynamic section is 8-byte aligned

Changed rodata_size from 4 to 8 bytes to ensure .dynamic section
virtual address is 8-byte aligned (required by sh_addralign=8).

Before: .dynamic at 0x19c (4-byte aligned) ❌
After:  .dynamic at 0x1a0 (8-byte aligned) ✅

Devnet deployment still fails with 'invalid dynamic section table',
suggesting the issue is deeper than section alignment. All structural
elements now match reference programs. Further debugging requires
white-box analysis of Solana CLI validation logic.
