test: run testcases with POSIX absolute paths on Windows

Some test cases are skipped on Windows by marking with POSIX prereq.
This is because arguments look like absolute paths (such as /a/b)
for regular Windows programs (*.exe executables, no bash scripts)
are changed to Windows paths (like C:/msysgit/a/b).

There is no cygpath nor equivalent on msysGit, but it is easy to
write one. New subcommand "mingw_path" is added in test-path-utils,
so that we can get the expected absolute paths on Windows. E.g.

COMMAND LINE                        Linux output  Windows output
==================================  ============  ===============
test-path-utils mingw_path /        /             C:/msysgit
test-path-utils mingw_path /a/b/    /a/b/         C:/msysgit/a/b/

With this utility, most skipped test cases in t0060 can be turned on
to be tested correctly on Windows.
