sparc64: vdso: Implement clock_gettime64()
To be y2038-safe, 32-bit userspace needs to explicitly call the 64-bit safe
time APIs.
Implement clock_gettime64() in the 32-bit vDSO.

sparc64: vdso: Switch to the generic vDSO library
The generic vDSO provides a lot common functionality shared between
different architectures. SPARC is the last architecture not using it,
preventing some necessary code cleanup.
Make use of the generic infrastructure.

sparc64: vdso: Move syscall fallbacks into header
The generic vDSO libraries expected the syscall fallbacks in
asm/vdso/gettimeofday.h. To prepare the adoption of the generic library,
move the existing functions there.
While at it, rename them so they match what the generic library expects.
