This test started failing on core-updates-frozen sometime after this commit:

https://git.savannah.gnu.org/cgit/guix.git/log/?id=727f05e1e285aa52f5a19ec923fdc2259859b4b1

It reports the wrong error message, with a lack of a leading "./" in the file name. So it
passes in that it correctly errors on the missing file, but has the wrong output. This
patch removes the test file to ignore the test.
