gnulib-tool.py: Fix misspelled option in output

[Bruno Haible]

Here's a fix for this test failure:

$ ./test-cache-1-8.sh
Files ./test-cache-1-8.result/lib/Makefile.am and 
tmp1858399-result/lib/Makefile.am differ
Files ./test-cache-1-8.result/m4/gnulib-cache.m4 and 
tmp1858399-result/m4/gnulib-cache.m4 differ
FAIL: gnulib-tool's result has unexpected differences.
