arm-toolchain/layer.conf: remove BB_DANGLINGAPPENDS_WARNONLY

This appears to be historical from when the toolchain was in meta-linaro.

It isn't needed anymore, there's one bbappend in meta-arm-toolchain for
grub which is part of oe-core, so will never be dangling.

This variable has a global effect, so leaving it in here has a negative
impact on users.

-* meta-arm-bsp
-
-  This layer contains machines for Arm reference platforms, for example FVP Base, N1SDP, and Juno.
-
-* meta-arm-toolchain
-
-  This layer contains recipes for Arm's binary toolchains (GCC and Clang for -A and -M), and a recipe to build Arm's GCC.
-
-* meta-atp
