linux/clocksource.h: Extract common header for vDSO
The vDSO library should only include the necessary headers required for
a userspace library (UAPI and a minimal set of kernel headers). To make
this possible it is necessary to isolate from the kernel headers the
common parts that are strictly necessary to build the library.
Split clocksource.h into linux and common headers to make the latter
suitable for inclusion in the vDSO library.
