buildBazelPackage: set $USER environment variable (#74538)

Browse source 
tensorflow assumes $USER to be set to something, otherwise it complains
like this:

```
FATAL: $USER is not set, and unable to look up name of current user: (error: 0): Success
Traceback (most recent call last):

```

Spotted while changing the hash of its fixed-output derivation on
purpose.

We could also set this in the tensorflow-specific part, but very likely,
other programs will fail as well.
