Fix race condition in package-bazel.sh

meteorcloudy · copybara-github · commit bddb191d3f99 · 2022-11-02T06:29:20.000-07:00
`bazel build -c //src:bazel.exe //src:bazel_nojdk.exe` sometimes output corrupted binaries on Windows. The reason is when we are executing the genrule for packaging the bazel zip files, we are writing a "file.list" file into the execroot, however there is no sandbox on Windows. So two actions are actually sharing the same path for the "file.list", this PR fixes the issue by writing the "file.list" file under the tmp dir. Fixes bazelbuild#16613 Closes bazelbuild#16614.
