unix: move functions Ptrace{Get|Set}RegSetArm64 to a separate file

Browse Source 
CL 204418 adds functions PtraceGetRegSetArm64 and PtraceSetRegSetArm64 to file
zptrace_armnn_linux.go, both of which depend on type Iovec. The definitions of type
Iovec on linux arm and arm64 are different, but file zptrace_armnn_linux.go is
shared by them. So these two functions cause compilation errors on linux arm. This
patch fixes this error by moving these two functions into a separate file.

Fixes golang/go#36032
