openmotif: remove due to lack of libxp in repository

ERROR: Nothing PROVIDES 'libxp' (but /home/hrw/HDD/devel/canonical/aarch64/meta-openembedded/meta-oe/recipes-support/openmotif/openmotif_2.3.3.bb DEPENDS on or otherwise requires it)
ERROR: Required build target 'openmotif' has no buildable providers.
