serf: stop scons trying to create directories in hosts rootfs

* since 1522f09a4d serf: cleanup recipe
  serf.do_install fails in builds with multilib enabled (with
  libdir=/usr/lib64 on host where /usr/lib64 doesn't exist)

DEBUG: Executing shell function do_install

ERROR: scons install execution failed.

* I don't know how exactly --install-sandbox is supposed to work but
  in this case it's trying to mkdir /usr/lib64 on the host rootfs
  which is clearly wrong and if I set LIBDIR together with
  --install-sandbox then the install paths are prefixed with $D twice
  in some cases (not for includedir and empty libdir at the end).
  So in the end I think it was an issue caused by the custom path
  validator in serf's SConstruct, removing that stops touching host
  and the installed paths (including the paths inside libserf*.pc)
  look correct
