[COMMUNITY] gles-user-module: fix dependencies

Users of gles-user-module can hit link issues since it does not have
libgbm and wayland-kms in its DEPENDS, but they are required to link
against the libraries it provides.  To fix this, add them to DEPENDS
per OpenEmbedded best practices.  Doing so requires spliting the EGL
headers into a separate recipe to avoid a circular dependency problem
with wayland-kms.

Bug-AGL: SPEC-429
