cmake: remove bogus CMAKE_LDFLAGS_FLAGS definition from toolchain file
As discussion in [YOCTO #14717] cmake contains a OEToolchainConfig.cmake
file to configure the toolchain correctly in cross-compile build for recipes
using cmake. The variable CMAKE_LDFLAGS_FLAGS is spelled incorrectly, cmake expects
CMAKE_SHARED_LINKER_FLAGS, CMAKE_STATIC_LINKER_FLAGS, CMAKE_EXE_LINKER_FLAGS and
CMAKE_MODULE_LINKER_FLAGS to be set instead. As cmake already correctly initializes
these from environment there is no need to specify the linker flags in the toolchain
file at all. So this just removes the variable, as its value was also set wrong.
