Subject: [PATCH] std: explicitly handle error.UnexpectedExitCode in
 build_runner

RunStep on unexpected exit code used to return error.UncleanExit, which
was confusing and unclear. When it was changed, the error handling code
in build_runner was not modified, which produced an error trace.

This commit explicitly handles error.UnexpectedExitCode in build_runner
so that the behavior now matches that of zig 0.8.1 after which it was
regressed.
