vdso: don't require 64-bit math in standalone test

Browse source 
The use of 64-bit math on i386 causes build failures:
vdso_standalone_test_x86.c:(.text+0x101): undefined reference to `__umoddi3'
vdso_standalone_test_x86.c:(.text+0x12d): undefined reference to `__udivdi3'

Commit adb19fb66e (Documentation: add makefiles for more targets) is
now building this by default, so it's failing the kernel build entirely.

Switching the declaration from uint64_t to time_t does the right thing
and handles the x32 case automatically.
