[build] Add optional build-id

Build-ids are required for doing certain kinds of performance tracing. For example build-ids let Linux perf find the correct objects and transfer them to other machines via "perf archive". This adds an option to add -Wl,--build-id to the linker. It can be enabled by passing -Dbuild_id=true to meson or --build-id to package-release.sh. Signed-off-by: Nicholas Fraser <[email protected]>
