*.patch: add Upstream-Status to all patches

There is new patch-status QA check in oe-core:
https://git.openembedded.org/openembedded-core/commit/?id=76a685bfcf927593eac67157762a53259089ea8a

This is temporary work around just to hide _many_ warnings from
optional patch-status (if you add it to WARN_QA).

This just added
Upstream-Status: Pending
everywhere without actually investigating what's the proper status.

This is just to hide current QA warnings and to catch new .patch files being
added without Upstream-Status, but the number of Pending patches is now terrible:

5 (26%) 	meta-xfce
6 (50%) 	meta-perl
15 (42%)        meta-webserver
21 (36%)        meta-gnome
25 (57%)        meta-filesystems
26 (43%)        meta-initramfs
45 (45%)        meta-python
47 (55%)        meta-multimedia
312 (63%)       meta-networking
