commit 8700e538cfe23c7ea61ca93cb4beea80f4acdf06

varnishtest: Replace macro_get() with macro_cat()

The latter operates on a VSB, which is always what call sites are doing
anyway. It also takes the responsibility of ignoring unknown macros, in
preparation for more responsibilities that will also require the ability
to fail a test case.
