Summary:
Koray reported issue with OpenNSA while using build VM and observed that we
don't hit the issue on devserver thanks to downloading the lfs cached file.

The root cause:

Broadcom added License notice and uploaded new 6.5.19 with same name.
This changed the hash though - causing fbcode builder to complain.
Fix it by adjusting the hash.

See the first line in the recursive diff of before vs. after: P134467317

(the broken symlinks is an unrelated existing issue, which we have reported to
Broadcom).
