Subject: Test to ensure less can parse the @import rewritten by css_loadfile()

This test is horrible, but I believe necessary to ensure that the
@import of less files actually works.

It is horrible as its not a unit test and its not a true functional
test.  It probably implies the code in css_out() should be refactored
to make it easier to test intermediate results.
