Have a common "capture file close alert box" routine.

Take cf_close_failure_alert_box() and put it into libui, with the name
cfile_close_failure_alert_box().  Use it not only in file.c but also
in ui/export_pdu_ui_utils.c, ui/gtk/file_import_dlg.c, and
ui/qt/import_text_dialog.cpp where the error we get back isn't
necessarily an errno.

Have ui/gtk/file_import_dlg.c and ui/qt/import_text_dialog.cpp also use
cfile_open_failure_alert_box() on open errors.
