[PATCH] rust: doctests: Use tabs for indentation in generated C code

[David Gow <davidgow@xxxxxxxxxx>]

While Rust uses 4 spaces for indentation, we should use tabs in the
generated C code. This does result in some scary-looking tab characters
in a .rs file, but they're in a string literal, so shouldn't make
anything complain too much.

Fixes: a66d733da801 ("rust: support running Rust documentation tests as KUnit ones")
