The definition of GNU_SOURCE was recently centralised in an upper layer kselftest Makefile, so the definition in the arm64 signal tests Makefile is no longer needed. To make things worse, since both definitions are not strictly identical, the compiler warns about it: <command-line>: warning: "_GNU_SOURCE" redefined <command-line>: note: this is the location of the previous definition
Drop the definition in the arm64/signal Makefile.
