On sparc64, when CONFIG_WERROR=y, there are a few missing-prototype
build errors. Fix them.
Add the 4 missing prototypes to <asm/vdso.h> and include that header
file in vclock_gettime.c.
Fixes these build errors:
In file included from ../arch/sparc/vdso/vdso32/vclock_gettime.c:22:
../arch/sparc/vdso/vdso32/../vclock_gettime.c:274:1: error: no previous
prototype for '__vdso_clock_gettime' [-Werror=missing-prototypes]

../arch/sparc/vdso/vdso32/../vclock_gettime.c:363:1: error: no previous
prototype for '__vdso_gettimeofday_stick' [-Werror=missing-prototypes]
