build: fix external patch application to not create .orig files

- Generation of patched original files (eg. dpdk-devbind.py.orig)
  causes build breakage of 'make install-ext-deps' on CentOS-8.
  Note: this only occurs on builds using 'make' for dpdk instead
  of 'meson'.  Thus only applies to stable/2009.

Type: fix
