logger/journald: fix SA4011: ineffective break statement
logger/journald: fix SA4011: ineffective break statement

This was introduced in 906b979b888cf9111a4a2583640e509d28395670, which changed
a `goto` to a `break`, but afaics, the intent was still to break out of the loop.
(linter didn't catch this before because it didn't have the right build-tag set)

    daemon/logger/journald/read.go:238:4: SA4011: ineffective break statement. Did you mean to break out of the outer loop? (staticcheck)
                break // won't be able to write anything anymore
                ^
