test/run.sh: Handle updated beauitful.init call in default config

While setting up an environment to run the integration tests in, the run.sh
script uses sed to generate versions of several files that refer to the
not-installed version of files. One of these needs to replace the call to
beautiful.init().

Before commit 20c9723c5b, the corresponding line was:

  beautiful.init("@AWESOME_THEMES_PATH@/default/theme.lua")

Now this wants to find and replace the following:

  beautiful.init(awful.util.get_themes_dir() .. "default/theme.lua")

To handle both versions, this commit adds some wildcards to the sed-expression
so that any line containing a call to beautiful.init is found and replaced.
