fix(ios-test): remove local keyword from top-level assignments

The script was using 'local' keyword outside of function scope,
which caused "local: can only be used in a function" error when
running test-phase2.sh. Removed 'local' from three variable
assignments (device_id and logs) at script top level, as 'local'
is only valid inside functions in bash/zsh.
