alpha: remove CONFIG_OSF4_COMPAT flag from syscall table
Remove CONFIG_OSF4_COMPAT config flag from system call table - systbls.S and to keep the same feature, add the flag in osf_sys.c. One of the patch in this patch series will generate the system call table file. In order to come up with a common implementation across all architecture, we need this change.
