Temporarily revert "Move pg_lzcompress.c to src/common."

This reverts commit 60838df922345b26a616e49ac9fab808a35d1f85.
That change needs a bit more thought to be workable.  In view of
the potentially machine-dependent stuff that went in today,
we need all of the buildfarm to be testing those other changes.
