pgsql: Remove broken PGXS code for pg_xlogdump

Remove broken PGXS code for pg_xlogdump

With the PGXS boilerplate in place, pg_xlogdump currently fails with an
ominous error message that certain targets cannot be built because
certain files do not exist.  Remove that and instead throw a quick error
message alerting the user of the actual problem, which should be easier
to diagnose that the statu quo.
