Marco Casaroli 3515e44845 libs/libc/machine/arm64: Do not dereference a NULL symbol in up_relocateadd(). 
libelf_relocateadd() passes sym as NULL for a relocation against symbol
index 0, such as R_AARCH64_NONE.  up_relocateadd() read sym->st_value
first, so loading a module with such a relocation faulted in the kernel.

Accept a NULL symbol for R_AARCH64_NONE and fail any other type, as the
other architectures do.
