libdrm: Remove dependency towards X11

Using this defconfig

BR2_x86_pentium_mmx=y
BR2_ENABLE_DEBUG=y
BR2_OPTIMIZE_2=y
BR2_TOOLCHAIN_BUILDROOT_LARGEFILE=y
# BR2_UCLIBC_INSTALL_UTILS is not set

BR2_PACKAGE_LIBDRM_NOUVEAU=y
BR2_PACKAGE_LIBDRM_VMWGFX=y

libdrm (w/o Intel API) compiles without BR2_PACKAGE_LIBATOMIC_OPS and without
BR2_PACKAGE_XLIB_LIBPCIACCESS, so USE_WCHAR, TOOLCHAIN_HAS_THREADS and
!BR2_PREFER_STATIC_LIB, previously added by the Xorg dependency, do not seem
to be necessary for libdrm at all.
