nonguix: multiarch-container: Handle empty shares env variable.

Browse Source 
Launching a package, like steam, with GUIX_SANDBOX_EXTRA_SHARES= (set to an
empty string) will cause guix shell to fail to launch with "guix shell: error:
statfs: : No such file or directory".

* nonguix/multiarch-container.scm (make-container-wrapper): Check that the
environment variable GUIX_SANDBOX_EXTRA_SHARES is both set and not an empty
string.
