ext/pgsql: Enable lo_tell64/lo_truncate64 by removing dead VE_PG_LO64 guards

The guards reference undefined VE_PG_LO64, a misspelling of
HAVE_PG_LO64 (removed in GH-14628), making the 64-bit code paths
permanently dead. Remove the guards to unconditionally enable the
64-bit variants for PostgreSQL >= 9.3, consistent with pg_lo_seek().

Dropped from GH-21386 as not suitable for backport.
