tests: use pdiff instead of diff for portability

Browse Source 
"diff" command might cause redundant message, "No differences

isn't portable, because POSIX specification doesn't define it.

pdiff script was introduced by f4cba8b2e7b4 to stabilize output of
standard diff command on each platforms.
