pg_upgrade: Fix inconsistency in memory freeing
The function in charge of freeing the memory from a result created by
PQescapeIdentifier() has to be PQfreemem(), to ensure that both
allocation and free come from libpq.
One spot in pg_upgrade was not respecting that for pg_database's
datlocale (daticulocale in v16) when the collation provider is libc (aka
datlocale/daticulocale is NULL) with an allocation done using
pg_strdup() and a free with PQfreemem(). The code is changed to always
use PQescapeLiteral() when processing the input.
Oversight in 9637badd9f92. This commit is similar to 48e4ae9a0707 and
5b94e2753439.
