zoneinfo: install tzdata.zi and leap-seconds.list

Build and install the tzdata.zi file and build the leapseconds file
from leap-seconds.list (installing both versions).  Third-party
software now expects these files to be installed.  OK sthen@ deraadt@

-# This file is in the public domain.

-# This file is generated automatically from the data in the public-domain
-# NIST format leap-seconds.list file, which can be copied from
-# <ftp://ftp.nist.gov/pub/time/leap-seconds.list>
-# or <ftp://ftp.boulder.nist.gov/pub/time/leap-seconds.list>.
-# The NIST file is used instead of its IERS upstream counterpart
-# <https://hpiers.obspm.fr/iers/bul/bulc/ntp/leap-seconds.list>
-# because under US law the NIST file is public domain
-# whereas the IERS file's copyright and license status is unclear.
-# For more about leap-seconds.list, please see
-# The NTP Timescale and Leap Seconds
-# <https://www.eecis.udel.edu/~mills/leap.html>.
-
-# The rules for leap seconds are specified in Annex 1 (Time scales) of:
-# Standard-frequency and time-signal emissions.
-# International Telecommunication Union - Radiocommunication Sector
-# (ITU-R) Recommendation TF.460-6 (02/2002)
-# <https://www.itu.int/rec/R-REC-TF.460-6-200202-I/>.
-# The International Earth Rotation and Reference Systems Service (IERS)
-# periodically uses leap seconds to keep UTC to within 0.9 s of UT1
-# (a proxy for Earth's angle in space as measured by astronomers)
-# and publishes leap second data in a copyrighted file
-# <https://hpiers.obspm.fr/iers/bul/bulc/Leap_Second.dat>.

-# There were no leap seconds before 1972, as no official mechanism
-# accounted for the discrepancy between atomic time (TAI) and the earth's
-# rotation.  The first ("1 Jan 1972") data line in leap-seconds.list
-# does not denote a leap second; it denotes the start of the current definition
-# of UTC.
-
-# All leap-seconds are Stationary (S) at the given UTC time.
-# The correction (+ or -) is made at the given time, so in the unlikely
-# event of a negative leap second, a line would look like this:
-# Leap	YEAR	MON	DAY	23:59:59	-	S
-# Typical lines look like this:
-# Leap	YEAR	MON	DAY	23:59:60	+	S
