Nathan Henrie 6014f26c47 Revert "Resolve symlink path for qemu directory if possible"
This reverts commit 6b6458916eaa51f0dbbcfeccd740706697697ad3 (Resolve
symlink path for qemu directory if possible).

Fully resolving the symlink to qemu solves some issues for
aarch64-darwin nix with regards to finding `edk2-aarch64-code.fd`, but
unfortunately the fully resolved path includes the version number,
making it so that even patch updates break the path to
homebrew-installed qemu files.

Fixes https://github.com/containers/podman/issues/18111

[NO NEW TESTS NEEDED]
