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

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 adb19fb66ee (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.
