Script to run WebPageReplay httparchive.go. This has a few advantages compared
to a direct go run:

1. Uses the bundled toolchain from DEPS, so it spares go installation. At the
same time, it spares knowing the details about the toolchain path, which is
architecture-dependent.

2. Can be run from outside the repo directory, while still resolving paths
   correctly.

   $ cd $CHROMIUM_SRC
   $ cat $CHROMIUM_SRC/input.txt
   Hi
   $ go run third_party/webpagereplay/src/httparchive.go \
      --some-input=input.txt
   Error: go.mod file not found
   $ go run -C third_party/webpagereplay src/httparchive.go \
      --some-input=input.txt
   Error: input.txt not found
   $ go run -C third_party/webpagereplay src/httparchive.go \
      --some-input=../../input.txt
   Success: input.txt found
   $ third_party/webpagereplay/script/run_httparchive.py \
      --some-input=input.txt
   Success: input.txt found

Note: why not make this run.py with --binary that can be "wpr" or "httparchive"?
To avoid handling run.py flags on top of the underlying binary flags.
