Jakob Unterwurzacher 2d01d5f2d4 tlog: always trim trailing newlines
The messages we print through tlog sometimes do, sometimes do
not contain a trailing newline. The stdlib logger usually drops
trailing newlines automatically, but tlog postfixes ColorReset to
the caller's message, so the logger logic does not work when we
print colored output.

Drop the newlines on our own, and add a test.

Fixes the blank lines in fsck output:
