This only saves ~32KB in the minimal linux/amd64 binary, but it's a
step towards permitting not depending on gvisor for small builds.

In df6014f1d7bf437adf239b75a62fd4c2f389ea2a we removed build tag
gating preventing importation, which tripped a NetworkExtension limit
test in corp. This was a reversal of
25f0a3fc8f6f9cf681bb5afda8e1762816c67a8b which actually made the
situation worse, hence the simplification.
This commit goes back to the strategy in
25f0a3fc8f6f9cf681bb5afda8e1762816c67a8b, and gets us back under the
limit in my local testing. Admittedly, we don't fully understand
the effects of importing or excluding importation of this package,
and have seen mixed results, but this commit allows us to move forward
again.
