Skip foreign tablespaces when running pg_checksums/pg_verify_checksums
Attempting to use pg_checksums (pg_verify_checksums in 11) on a data
folder which includes tablespace paths used across multiple major
versions would cause pg_checksums to scan all directories present in
pg_tblspc, and not only marked with TABLESPACE_VERSION_DIRECTORY. This
could lead to failures when for example running sanity checks on an
upgraded instance with --check. Even worse, it was possible to rewrite
on-disk pages with --enable for a cluster potentially online.
This commit makes pg_checksums skip any directories not named
TABLESPACE_VERSION_DIRECTORY, similarly to what is done for base
backups.
