Don't translate program name directive in Pascal file template

Pascal code only accepts an identifier in the program name directive,
but {untitled} wildcard gets replaced with a translated string that may
not be a valid Pascal identifier.  Moreover, the directive being part
of the source of the program it's good practice for it to be in English
anyway.

Closes #3602314.
