[PATCH] glib-networking: Support building with USE_NLS=no

[Mike Crowe <mac@mcrowe.com>]

As reported in
http://lists.openembedded.org/pipermail/openembedded-core/2019-February/279344.html
, glib-networking no longer configures successfully if USE_NLS="no":

| po/meson.build:1:5: ERROR:  Can not do gettext because xgettext is not installed.

In the current absence of anything better, it seems that this can be
overcome by telling Meson not to look in the po/ directory.
