tests: use double quote to quote arguments in hook for portability

On windows, single quote doesn't work as quote character in hook
command line, because "cmd.exe" doesn't recognize it as quoting
character. And this causes failure of test.

This patch uses double quote to quote arguments in hook instead of
single quote for portability.

Even though single quotes for "[hooks] pretxncommit" in
test-clone-pull-corruption.t seems to work correctly (may MinGW sh
treat specially ?) AFAIK, this patch also replaces them by double
quotes for consistency.

 Verify that pending changesets are seen by pretxn* hooks but not by other
 processes that access the destination repo while the hooks are running.
 
 The hooks (python and external) both reject changesets after some think time,
 during which another process runs pull.  Each hook creates a file ('notify') to
 indicate to the controlling process that it is running; the process removes the
 file to indicate the hook can terminate.
