kselftest/arm64: Include <asm/ptrace.h> for user_gcs definition 

kselftest includes kernel uAPI headers with option:

  -isystem $(top_srcdir)/usr/include

Include <asm/ptrace.h> in libc-gcs.c for the definition of struct
user_gcs from the uAPI headers, and remove the redundant definition in
gcs-util.h. This fixes a compilation error on systems where the
toolchain defines NT_ARM_GCS.
