Add Makefile to invoke the system call table generation script which is placed in scripts directory as a common location acc- essible for all the architectures.
scripts/syscallhdr.sh will generate uapi header and scripts- /syscalltbl.sh will generate kapi header respectively. There is another scripts scripts/syscallnr.sh can generate total number of syscall which doesn't invoke from this Makefile.
