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.
