tests: invoke printenv.py via sh -c for test portability

On Windows platform, invoking printenv.py directly via hook is
problematic, because:

  - unless binding between *.py suffix and python runtime, application
    selector dialog is displayed, and running test is blocked at each
    printenv.py invocations

  - it isn't safe to assume binding between *.py suffix and python
    runtime, because application binding is easily broken

    For example, installing IDE (VisualStudio with Python Tools, or
    so) often requires binding between source files and IDE itself.

This patch invokes printenv.py via sh -c for test portability. This is
a kind of follow up for d19787db6fe0, which eliminated explicit
"python" for printenv.py. There are already other 'sh -c "printenv.py"'
in *.t files, and this fix should be reasonable.

This changes were confirmed in cases below:

  - without any application binding for *.py suffix
  - with binding between *.py suffix and VisualStudio

This patch also replaces "echo + redirection" style with "heredoc"
style, because:

  - hook command line is parsed by cmd.exe as shell at first, and
  - single quotation can't quote arguments on cmd.exe, therefore,
  - "printenv.py foobar" should be quoted by double quotation, but
  - nested quoting (or tricky escaping) isn't readable

  We have conflicts in the following files:
  ./a
  $ sleep 1
  $ echo e > a
  $ echo f > f
  $ mkdir dir
  $ echo d > dir/d
  $ echo d > dir/d2
  $ darcs record -a -l -m p2
  Finished recording patch 'p2'

test file and directory move

  $ darcs mv f ff

Test remove + move

  $ darcs remove dir/d2
  $ rm dir/d2
  $ darcs mv dir dir2
  $ darcs record -a -l -m p3
  Finished recording patch 'p3'

The converter does not currently handle patch conflicts very well.
When they occur, it reverts *all* changes and moves forward,
letting the conflict resolving patch fix collisions.
Unfortunately, non-conflicting changes, like the addition of the
"c" file in p1.1 patch are reverted too.
Just to say that manifest not listing "c" here is a bug.
