Subject: [PATCH] wamrc: 2.3.1 -> 2.4.4

This build was failing due to needing access to files outside the
`wamr-compiler` directory, so we `cd` into the build directory instead
of using `sourceRoot`.

Additionally, this fails to link with LLVM 21, so we override the LLVM
version to override it to LLVM 20. Example failing Hydra build:
