[PATCH] kunit: tool: fix --raw_output to actually show output

From: Daniel Latypov
Date: Fri Oct 30 2020 - 02:17:23 EST


Currently --raw_output means nothing gets shown.
Why?
Because `raw_output()` has a `yield` and therefore is a generator, which
means it only executes when you ask it for a value.

Given no one actually is using it as a generator (checked via the added
type annotation), drop the yield so we actually print the output.

Also strip off the trailing \n (and any other whitespace) to avoid
[<601d6d3a>] ? printk+0x0/0x9b

[<601e5058>] ? kernel_init+0x23/0x14b

[<600170d2>] ? new_thread_handler+0x82/0xc0
making the output unreadable.
