The version number calculated by read_pg_version_file() is multiplied
once by 10000, to be able to do comparisons based on PG_VERSION_NUM or
equivalents with a minor version included. However, the version number
given sync_pgdata() was multiplied by 10000 a second time, leading to an
overestimated number.
This issue was harmless (still incorrect) as pg_combinebackup does not
support versions of Postgres older than v10, and sync_pgdata() only
includes a version check due to the rename of pg_xlog/ to pg_wal/. This
folder rename happened in the development cycle of v10. This would
become a problem if in the future sync_pgdata() is changed to have more
version-specific checks.
Oversight in dc21234005, so backpatch down to v17.
