Fix a bug in run_tool_with_logging script

Fix the case when call a tool with run_tool_with_logging with a single
arg start with -- (e.g. adb --help), make sure when we pass that arg
to the logger, it treat it as the value for the --tool_args option
instead of a separate option

Test: atest run_tool_with_logging_test
Test: manually run source build/envsetup.sh and run adb --help and check
the event log is sent to clearcut. Tested with both bash and zsh
