POSIX's diff(1) requires output in normal diff format.
However, busybox's diff's output is written in unified format.

POSIX requires no option for normal-diff format.

A hint in test-lib-functions::test_cmp said `diff -u` isn't available

Workaround this problem by assuming `diff(1)` output is unified
if we couldn't make anything from normal-diff format.
