request patch pg_recvlogical.c, pg_receivexlog.c for nls

Hello,

at PostgreSQL version 9.5rc1,
at line 934 in pg_recvlogical.c 

        set_pglocale_pgservice(argv[0],PG_TEXTDOMAIN("pg_recvlogical"));

this references invalid catalog file, because pg_basebackup,
pg_recvlogical, pg_receivexlog commands use same catalog file
pg_basebackup.mo

pg_receivexlog.c too.

patch please.
