Fix incorrect pg_proc.proallargtypes entries for two built-in functions.

pg_sequence_parameters() and pg_identify_object() have had incorrect
proallargtypes entries since 9.1 and 9.3 respectively.  This was mostly
masked by the correct information in proargtypes, but a few operations
such as pg_get_function_arguments() (and thus psql's \df display) would
show the wrong data types for these functions' input parameters.

In HEAD, fix the wrong info, bump catversion, and add an opr_sanity
regression test to catch future mistakes of this sort.

In the back branches, just fix the wrong info so that installations
initdb'd with future minor releases will have the right data.  We
can't force an initdb, and it doesn't seem like a good idea to add
a regression test that will fail on existing installations.
