Log: Remove __restrict qualifiers from syscalls.master. 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.
