    Fix tst-timezone race (bug 14096).

    I observed a failure of timezone/tst-timezone with the same symptoms
    as reported in bug 14096.

    I was unable to reproduce the failure on testing again.  However, from
    inspection, the cause is as follows.  tst-timezone uses time zones
    compiled from the northamerica file, but has no dependency on any such
    zones, so with a parallel build it is possible that they do not get
    compiled until after tst-timezone is run.  This patch adds a
    dependency on the compiled America/New_York zone (the one used as a
    makefile target to cause such zones to be compiled, rather than one
    which is actually used in that test) to fix the race.

    Tested for x86_64.

        [BZ #14096]
        * timezone/Makefile ($(objpfx)tst-timezone.out): Depend on
        America/New_York.
