Make /etc/localtime a direct symlink to the zoneinfo file

Browse source 
Some programs (notably the Java Runtime Environment) expect to be able
to extract the name of the time zone from the target of the
/etc/localtime symlink.  That doesn't work if /etc/localtime is a
symlink to /etc/static/localtime.  So make it a direct symlink.
