Hi guix,

Discovered following behaviour while setting up GNUnet CI:

Given

./gnu/packages/a.scm:
   ...
   (source (local-file (dirname (current-filename))))
   ...

export GUIX_PACKAGE_PATH=3D$PWD

`(current-filename)` returns `#f` when evaluated via `guix environment`,
while `guix build` does fine. Is this expected? Am I doing something wron=
g?

The usecase is like
