asm-generic syscall fix for 4.6-rc

Browse Source 
My last pull request for asm-generic had just one patch that added two
 new system calls to asm/unistd.h, but unfortunately it turned out
 to be wrong, pointing arch/tile compat mode at the native handlers
 rather than the compat ones.
 
 This was spotted by Yury Norov, who is working on ILP32 mode
 for arch/arm64, which would have the same problem when merged.
 This fixes the table to use the correct compat syscalls, like
 the other 64-bit architectures do.
 
 I'll try to find the time to come up with a solution that
 prevents this problem from happening again, by allowing all
 future system calls to just get added in a single file
 for use by all architectures.
