tests: invoke hg command indirectly from shell script to run on Windows

Before this patch, test-tag.t can't run successfully on Windows,
because:

  - quoted hg command ('"hg"') prevents "hg.bat" from working correctly
    (only at testing with pure Python build)

    "%~f0" and "%~dp0hg" in "hg.bat" cause unexpected result in this
    case. BTW, quoted "\path\to\hg" works correctly.

  - "`pwd`" in the command line is expanded unexpectedly

    not "C:\path\to\TESTTMP" but "C;C:\path\to\TESTTMP"
