    zoneinfo: fix makefile rules script
    
    In make target rules, one needs to use subshell if there are
    change directory commands that should only have an effect on the
    other commands in the same line. Otherwise, if make is not running in
    compatibility mode (for example, when -j flag is specified), commands
    would be executed in a single shell and lines following the "cd" might
    not work as expected.
    
    Adjust the target script lines that use "cd" to run in a subshell
    by adding appropriate parenthesis.
