tests: use portable diff script via extdiff extension

Before this patch, some tests using external "diff" command via
extdiff extension fail on Solaris, because of incompatibility of
"diff" command and its output.

For example, system standard "diff" (= /usr/bin/diff) on Solaris
differs from GNU diff in points below:

  - "-N" (treat absent files as empty) option isn't supported

  - files are examined not in dictionary order
    (maybe, in order in storage)

This patch introduces portable diff script "pdiff" and make tests use
it via extdiff extension.

For portability of tests, this patch invokes "pdiff" script with
explicit "sh", because standard shell of runtime platform ("cmd.exe"
on Windows) is used at first to invoke external diff command.
