guix: Let texlive importer handle linked scripts.

* guix/import/texlive.scm (tlpdb): Also retrieve so-called binfiles.
(formats):
(linked-scripts): New functions.
(tlpdb->package): Use new functions to set #:LINK-SCRIPTS argument and
possibly INPUTS.
* tests/texlive.scm (%fake-tlpdb): Add test data.
("texlive->guix-package, single script, no extension"):
("texlive->guix-package, multiple scripts, with extensions"):
("texlive->guix-package, script with associated input"):  New tests.
