Bazel client: reduce dependency on <unistd.h>

In this change:

- rename WriteFileToStreamOrDie to
WriteFileToStderrOrDie (since we only ever used it
for stderr)

- replace open/write/read/close operations with
blaze_util::ReadFile/WriteFile

- wrap ToString(getpid()) in a utility function

- move SyncFile to file_<platform>
