Fix one more portability shortcoming in new test_pg_dump test.

If the bootstrap superuser's name requires quoting, regroleout
will supply double quotes ... but the result of CURRENT_USER
is just the literal name.  Apply quote_ident() to ensure a match.

Per Andrew Dunstan's off-list investigation of buildfarm member
prion's failures.
