Remove __restrict qualifiers from syscalls.master.

Browse Source 
The restruct qualifier is intended to aid code generation in the
compiler, but the only access to storage through these pointers is via
structs using copyin/copyout and the like which can not be written in C
or C++ and thus the compiler gains nothing from the qualifiers.

As such, the qualifiers add no value in current usage.
