pgsql: Avoid duplicate file references in backend .pot file

Avoid duplicate file references in backend .pot file

The list of files for the backend's message catalog is collected with
find, which also listed symlinks, namely the generated files that are
linked from src/include/utils/ to src/backend/utils/ (such as
guc_tables.inc.c) and the port/pg_sema.c and port/pg_shmem.c links
created by configure. Since the link targets are found under their
real names as well, xgettext processed those files twice, resulting in
duplicate "#:" references like

#: ../include/utils/guc_tables.inc.c:410 utils/guc_tables.inc.c:410

Fix by restricting find to regular files.
