bug#62018: 30.0.50; (require 'dbus) hangs in batch mode when called through execute-kbd-macro

[Spencer Baugh]

1. emacs --batch --eval '(execute-kbd-macro (read-kbd-macro "M-:
(require SPC (quote SPC dbus)) RET"))'
2. Observe that it hangs forever.

Note that this doesn't need to be direct; running any command through
execute-kbd-macro which eventually loads dbus will hang indefinitely.
(battery), for example.

This may seem like an odd thing to do, but I use execute-kbd-macro to
run tests for keybindings in my Emacs packages.

This issue appears to also happen on Emacs 28 and Emacs 27.

That change fixes my minimal reproducer (sent in the initial email) and
also fixes my larger test framework based on execute-kbd-macro.

Thank you!
