[libvirt] [PATCH] src: Include $(builddir)/util in the header search path

[Andrea Bolognani]

Since a9fe620372144db, we are generating virkeymaps.h at build
time; however, we are not including $(builddir)/util in the
header search path, so when doing a VPATH build the compiler
is unable to locate the file.

make[2]: Entering directory

Tested by

  * running 'git clean -xdf' in the source directory
  * running './autogen.sh'
  * running 'make distclean'
  * making sure src/util/virkeymaps.h did not exist
  * moving to an empty build directory
  * running '../libvirt/configure'
  * running 'make check'
  * running 'make distcheck'

This is another take on the problem Michal's trying to solve with

The commit message is "inspired" by his ;)
