python-psutil: update to version 5.9.0, fix build on macos

1. updated to 5.9.0

2. psutil can not be built on macos due to build script detects Darwin
using sys.platform and changes build logic to build for Darwin, but
OpenWrt is Linux.
This commit add patch to allow redefining sys.platform and uses
env var TARGET_SYS_PLATFORM to specify linux as sys platfrom.

+Subject: [PATCH] Add cross-platform build ability
+
+Currently it is not possible to build psutil on MacOS for Linux
+target using external toolchain. It fails due to build script
+detects build host OS and changes build logic according to detected
+OS.
+
+This patch allows to redefine os.name and sys.platform using ENV
+vars TARGET_OS_NAME and TARGET_SYS_PLATFORM. If these variables
+are not defined then os.name and sys.platform is used as it does
+currently.
+
+Using this patch it is possible to compile psutil on MacOS with
+OpenWrt GCC Toolchain (OpenWrt is Linux).
