[PULL 4/9] configure: Add missing POSIX-required space

[Peter Maydell]

In commit 7d7dbf9dc15be6e1 we added a line to the configure script
which is not valid POSIX shell syntax, because it is missing a space
after a '!' character. shellcheck diagnoses this:

if !(GIT="$git" "$source_path/scripts/git-submodule.sh" 
"$git_submodules_action" "$git_submodules"); then
    ^-- SC1035: You are missing a required space after the !.

and the OpenBSD shell will not correctly handle this without the space.

Fixes: 7d7dbf9dc15be6e1 ("configure: replace --enable/disable-git-update with 
--with-git-submodules")
