Add 16KB page size support for Android builds

[alexander-zubkov]

What was done

• Updated build configuration to align segments to 16KB memory pages.
• This ensures compatibility with newer Android devices that use 16KB page size.

Why

Without this change, the fbclient library fails to load on devices with 16KB memory pages.

How it was tested

• Verified using llvm-readelf -l libfbclient.so on the built artifacts — alignment shows 0x4000 (16KB).
• Deployed on Android arm64 device — the application runs without crashes.
