installer/portable: also install a redirector for /bin/sh.exe

It was pointed out in git-for-windows/git#208
that SourceTree expects `/bin/sh.exe` to be available. Let's just
install the redirector to make SourceTree happy, too.

This is a companion patch to fd137f7 (installer/portable: copy
redirectors into /bin/{bash,git}.exe, 2015-06-19).
