t4002: fix "diff can read from stdin" syntax

I noticed this test was producing output like ``` t4002-diff-basic.sh: test_expect_successdiff can read from stdin: not found ``` which is rather odd. Investigation shows an error of shell syntax: foo'abc' is the same as fooabc to the shell. Perhaps obviously, this is not a valid command for the test. I am surprised this doesn't count as an error in the test, but that accounts for it going unnoticed. Signed-off-by: D.
