fix: ReZygiskd out-of-bounds write due to too small system_arch buffer

Browse Source 
This commit fixes the issue where when the "ro.product.cpu.abilist" prop has a value bigger than 31 characters, which mostly happens in WSA (Windows Subsystem For Android) as it can support 5+ architectures, it will write outside the buffer, leading to undefined behavior, but most of the time crashes.
