Обсуждение: pgsql: Get rid of useless global variable in pg_upgrade.

Get rid of useless global variable in pg_upgrade.

Since the scandir() emulation was taken out of pg_upgrade, there's
no longer any need for scandir_file_pattern to exist as a global
variable.  Replace it with a local in the one remaining function
that was making use of it.
