Escape * in build-debug before passing to debug

With `setopt nonomatch` unescaped `*` can be used in command arguments
however when passing command arguments to `build-debug` the `*` _should_
be escaped so that the debugger e.g. `gdb` will correctly invoke the
program where `setopt nonomatch` does not apply.
