DynamicLoader: Disable stack protector in some files for aarch64 build
The code would access the __stack_chk_guard variable in main.cpp and
LibELF/Relocation.cpp before the loader was able to relocate itself, so
this commit disable the stack protector for the aarch64 build to make
sure that no accesses to __stack_chk_guard are inserted.
