[bugfix](k8s) fix fe.out not generated when start_fe.sh --console (#61807)
pick from https://github.com/apache/doris/pull/60522/changes
When running FE in console mode (start_fe.sh --console), the fe.out log
file was not generated because stdout/stderr were not redirected to the
log file.
The root cause is that the log4j console appender was configured with
target="SYSTEM_OUT", which sends log4j logs to stdout. This makes it
impossible to separate log4j logs from JVM stdout output at the shell
level.
Fix:
1. Change log4j console appender target from SYSTEM_OUT to SYSTEM_ERR in
Log4jConfig.java, so that log4j logs go to stderr (displayed on
terminal) instead of stdout. This also matches the env var name
DORIS_LOG_TO_STDERR.
2. Redirect stdout to fe.out in start_fe.sh console mode, consistent
with daemon mode behavior. The fe.out file now only contains JVM native
output, not log4j formatted logs.
