tests: Import (guix build syscalls) when (guix build store-copy) is used.

Fixes a test failure introduced in
189525412e3d803f3f77e15ec4a62aaa57f65a2d.

* guix/progress.scm: Autoload (guix build syscalls).
* tests/gexp.scm ("gexp->derivation, store copy"): Add (guix build
syscalls) to the list of imported modules.  Use ‘with-imported-modules’
rather than #:modules.
