media-gfx/wings: Drop alpha keyword

!!! All ebuilds that could satisfy ">=media-libs/mesa-9.1.6[opencl,abi_x86_32(-)?,abi_x86_64(-)?,abi_x86_x32(-)?,abi_mips_n32(-)?,abi_mips_n64(-)?,abi_mips_o32(-)?,abi_ppc_32(-)?,abi_ppc_64(-)?,abi_s390_32(-)?,abi_s390_64(-)?]" have been masked.
!!! One of the following masked packages is required to complete your request:
- media-libs/mesa-9999::gentoo (masked by: missing keyword)

(dependency required by "virtual/opencl-0-r4::gentoo" [ebuild])
(dependency required by "dev-libs/cl-1.2.1-r1::gentoo" [ebuild])
(dependency required by "=dev-libs/cl-1.2.1-r1" [argument])

This is a result of:

RDEPEND="app-eselect/eselect-opencl
    || (
        >=media-libs/mesa-9.1.6[opencl,${MULTILIB_USEDEP}]
        video_cards_fglrx? (
            >=x11-drivers/ati-drivers-12.1-r1 )
        video_cards_nvidia? (
            >=x11-drivers/nvidia-drivers-290.10-r2 )
        abi_x86_64? ( !abi_x86_32? ( dev-util/intel-ocl-sdk ) )
    )"

This is just not satisfiable on Alpha at the moment. Also, wings has never been
stable on alpha (and is a bit niche), so I'll drop the alpha keyword for 1.1.1
and opt Alpha out.
