Subject: [PATCH 3/3] remove dmraid while compiling with --with-dm

Fix the following failure:

...
Perhaps you should add the directory containing `dmraid.pc'
to the PKG_CONFIG_PATH environment variable
No package 'dmraid' found
...

...
../../../git/src/plugins/dm.c:24:10: fatal error: dmraid/dmraid.h: No
such file or directory
 #include <dmraid/dmraid.h>
          ^~~~~~~~~~~~~~~~~
...

Upstream-Status: Inappropriate [oe specific]
