Subject: [PATCH] test: add simple check for kernel-cmdline stage

Add a stage test to check that the new kopts stage is creating the
target file /etc/kernel/cmdline with the right content. Since tree
diff currently seems to lack support for content hashing new files
we work around this by creating first an empty /etc/kernel/cmdline
file and then get a content diff with the desired options set.
