[ Upstream commit 3aa415dd2128e478ea3225b59308766de0e94d6b ]

The get_metadata() test requires real root, so let's skip it if we're not real root.

Note that I used XFAIL here because that's what the test does later if CONFIG_CHEKCKPOINT_RESTORE happens to not be enabled. After looking at the code, there doesn't seem to be a nice way to skip tests defined as TEST(), since there's no return code (I tried exit(KSFT_SKIP), but that didn't work either...). So let's do it this way to be consistent, and easier to fix when someone comes along and fixes it.
