fix(ci/edriver): add -L native=/usr/lib to RUSTFLAGS for zstd on Alpine

'-l static=zstd' in RUSTFLAGS causes rustc to validate the library
exists at compile-time for every crate (including pure-Rust libs like
cfg-if). Without an explicit -L path, rustc cannot locate libzstd.a
and errors with 'could not find native static library zstd'.

Fix: add '-L native=/usr/lib' alongside '-l static=zstd' so rustc
knows where to find /usr/lib/libzstd.a (provided by zstd-static).
