[PATCH weston] Fix runtime error caused by missing header inclusion

[Joh, Yong-Il (Tolkien)]

Hi all.

when I run weston on yocto for qemux86 device,
there is an error with following.

[08:02:07.897] launching '/usr/lib/weston/weston-ivi-shell-user-interface'
[08:02:08.201] /usr/lib/weston/weston-ivi-shell-user-interface died on signal 11

it is caused everytime
when I build yocto software on Ubuntu 12.04 64bit desktop for qemux86 device. (not qemux86-64)

to resolve this,
apply following patch.
