AOSCOS: MIPS: remove duplicate defines of NR_syscalls

In "FROMLIST: MIPS: Add syscall auditing support", some duplicate
defines of NR_syscalls were added to arch/mips/include/asm/unistd.h,
which were already added by
1d7bf99 ("MIPS: ftrace: Add support for syscall tracepoints.").

Removing the duplicate defines of NR_syscalls.
