archivers/liblz4: revert switch to meson

This partially reverts commit 7d6061f15551dcde40cf70fd743d631095360a23
made in the year 2020.

Reason: lang/python314 newly depends on archivers/zstd,
which depends on archivers/liblz4, so neither of the latter two
can use any Python to build lest we create a circular dependency
when Python 3.14 is made the default.

Note: make-based builds remain the documented way
to build/test lz4 1.10.0 in their primary documentation.

Note also that the meson build installed one file less than the
make-based build, which gets re-added, hence bumping PORTREVISION.
