Add bazel-distfile for 0.5.0 with extra sed fix

Original 0.5.0 used 'sed -E' in the scripts/bootstrap/compile.sh but that fails
on forge as we only have ancient sed (years 2000 - 2006) there. I created a new
distfile that is (as far as I can tell) identical to 0.5.0, plus I added a
cherry pick for the sed fix.

To create identical bazel tree I used:

```
devtools/blaze/bazel/admin/release.sh create 0.5.0 f3ae88ee043846e7acdffd645137075a4e72c573 c58ba098526b748f9c73e6229cafd74748205aa1 0acead4ea3631240659836ce6ecd6d7f67fd352b   d0242ce4a87929f2528f4602d0fb09d1ccfcea94 d953ca8b87a46decbce385cebb446ae0dd390881 755669fb5de1f4e762f27c19776cac9f410fcb94 6f041661ca159903691fcb443d86dc7b6454253d  720561113bfa702acfc2ca24ce3cc3fd7ee9c115 511c35b46cead500d4e76706e0a709e50995ceba 8470be1122825aae8ad0903dd1e1e2a90cce47d2  4a404de2c6c38735167e17ab41be45ef6fc4713a 36ce4b433e19498a78c34540d5a166d4e0006b22 38949b8526bdb3e6db22f3846aac87162c28c33f 1a57d298f8aa6ea8136d93223902104f2479cd2a eb565f408e03125e92d42b00756e519795be6593 39f328cf392056618d1a3ead4835a138b189a06d 624802893f4fe72118f00a78452605d41a2e1c6f c4f271d1a68366b6fa5ff38ea7d951b6a22af044 926180997a0f296a5a009326aead887279ce0a90 baca6e4cb023649920871b74810927d304729e59 866ecc8c3d5e0b899e3f0c9c6b2265f16daae842 cc21998c299b4d1f97df37b961552ff8168da17f  0f0ccc4fc8229c1860a9c9b58089d6cfb2ee971f  3b08f774e7938928e3a240a47a0a7554cdc8d50b 3566474202d1978acfdcb7e5ff73ee03ea6f3df9
```

Then I went into ~/os-blaze-release and run:

```
bazel --bazelrc=/dev/null --nomaster_bazelrc build \                                                                                                                                                                                     1 ↵
      --embed_label=0.5.0_with_sed_fix --stamp \
      --workspace_status_command=scripts/ci/build_status_command.sh \
      --define JAVA_VERSION=1.8 \
      //:bazel-distfile
```

And finally I copied `bazel-genfiles/bazel-distfile.zip` to this repo.
