Add prefix checks in exclude lists for pg_rewind, pg_checksums and base backups
An instance of PostgreSQL crashing with a bad timing could leave behind
temporary pg_internal.init files, potentially causing failures when
verifying checksums. As the same exclusion lists are used between
pg_rewind, pg_checksums and basebackup.c, all those tools are extended
with prefix checks to keep everything in sync, with dedicated checks
added for pg_internal.init.
Backpatch down to 11, where pg_checksums (pg_verify_checksums in 11) and
checksum verification for base backups have been introduced.
