[PATCH] tzdata: Update to version 2026b

[Adolf Belka <adolf.belka@ipfire.org>]

- Update from version 2026a to 2026b
- No change in rootfile
- Changelog
    2026b
  Briefly:
    British Columbia moved to permanent -07 on 2026-03-09.
    Some more overflow bugs have been fixed in zic.
  Changes to future timestamps
    British Columbia’s 2026-03-08 spring forward was its last
     foreseeable clock change, as it moved to permanent -07 thereafter.
     (Thanks to Arthur David Olson.)  Although the change to permanent
     -07 legally took place on 2026-03-09, temporarily model the change
     to occur on 2026-11-01 at 02:00 instead.  This works around a
     limitation in CLDR v48.2 (2026-03-17).  This temporary hack is
     planned to be removed after CLDR is fixed.
  Changes to code
    zic no longer mishandles a last transition to a new time type.
    zic no longer overflows a buffer when generating a TZ string like
     "PST-167:59:58PDT-167:59:59,M11.5.6/-167:59:59,M12.5.6/-167:59:59",
     which can occur with adversarial input.  (Thanks to Naveed Khan.)
    zic no longer generates a longer TZif file than necessary when
     an earlier time zone abbreviation is a suffix of a later one.
     As a nice side effect, zic no longer overflows a buffer when given
     a long series of abbreviations, each a suffix of the next.
     (Buffer overflow reported by Arthur Chan.)
    zic no longer overflows an int when processing input like ‘Zone
     Ouch 2147483648:00:00 - LMT’.  The int overflow can lead to buffer
     overflow in adversarial cases.  (Thanks to Naveed Khan.)
    zic now checks for signals more often.
