30521d5126 cmd/link: produce valid binaries with large data section on wasm
CL 170950 had a regression that makes the compiler produce
an invalid wasm binary if the data section is too large.
Loading such a binary gives the following error:
"LinkError: WebAssembly.instantiate(): data segment is out of bounds"

This change fixes the issue by ensuring that the minimum size of the
linear memory is larger than the end of the data section.

Fixes #34395.
