Dan McGee 3559306546 scripts: allow usage when gettext is not installed
Address the issue of our scripts not working so great when gettext is not
available. This has come up in multiple bug reports, and is relatively easy
to address by adding a simple check and a stub function if gettext was not
found that simply echos the original message.

Addresses concerns from FS#9214 and FS#9607.
