mips: syscalls: define syscall offsets directly in <asm/unistd.h>

Browse Source 
There is no good reason to generate the syscall offset macros by
scripting since they are not derived from the syscall tables.

Define __NR_*_Linux macros directly in arch/mips/include/asm/unistd.h,
and clean up the Makefile and the shell script.
