Subject: rustbuild: make backtraces (RUST_BACKTRACE) optional

but keep them enabled by default to maintain the status quo.

When disabled shaves ~56KB off every x86_64-unknown-linux-gnu
binary.

To disable backtraces you have to use a config.toml (see
src/bootstrap/config.toml.example for details) when building rustc/std:

$ python bootstrap.py --config=config.toml
