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

Make sure import still works with branch information in patches.
