archivers/gzip: Update to version 1.14

* Noteworthy changes in release 1.14 (2025-04-09) [stable]

** Bug fixes
  'gzip -d' no longer omits the last partial output buffer when the
  input ends unexpectedly on an IBM Z platform.
  [bug introduced in gzip-1.11]
  'gzip -l' no longer misreports lengths of multimember inputs.
  [bug introduced in gzip-1.12]
  'gzip -S' now rejects suffixes containing '/'.
  [bug present since the beginning]

** Changes in behavior
  The GZIP environment variable is now silently ignored except for the
  options -1 (--fast) through -9 (--best), --rsyncable, and --synchronous.
  This brings gzip into line with more-cautious compressors like zstd
  that limit environment variables' effect to relatively innocuous
  performance issues.  You can continue to use scripts to specify
  whatever gzip options you like.
  'zmore' is no longer installed on platforms lacking 'more'.

** Performance improvements
  gzip now decompresses significantly faster by computing CRCs via a
  slice by 8 algorithm, and faster yet on x86-64 platforms that
  support pclmul instructions.

* Noteworthy changes in release 1.13 (2023-08-19) [stable]

** Changes in behavior
  zless now diagnoses gzip failures, if using less 623 or later.
  When SIGPIPE is ignored, gzip now exits with status 2 (warning)
  instead of status 1 (error) when writing to a broken pipe.  This is
  more useful with programs like 'less' that treat gzip exit status 2
  as a non-failure.

** Bug fixes
  'gzip -d' no longer fails to report invalid compressed data
  that uses a dictionary distance outside the input window.
  [bug present since the beginning]
  Port to C23, which does not allow K&R-style function definitions
  with parameters, and which does not define __alignas_is_defined.
