ktest: Resolve LOG_FILE in test option context

LOG_FILE is expanded immediately after the config file is parsed with
eval_option(..., -1). That uses the default context, not the same option
resolution path used for tests. If LOG_FILE depends on options that are
finalized per test, it can be resolved from stale values before the first
test starts.

Resolve LOG_FILE through set_test_option("LOG_FILE", 1) instead so it uses
the same expansion rules as the rest of the test options.
