[hurd,commited] tst-sprintf-errno: Update Hurd message output

[Samuel Thibault]

03ad444e8e08 ("mach: Fix incoherency between perror and strerror")
fixesd the output of error messages, but tst-sprintf-errno.c was still
checking the old (erroneous) format. This updates the expected output
according to the 03ad444e8e08 fix.
