vdso: Fix powerpc build U64_MAX undeclared error

Browse Source 
U64_MAX is not in include/vdso/limits.h, although that isn't noticed on x86
because x86 includes include/linux/limits.h indirectly. However powerpc is
more selective, resulting in the following build error:

  In file included from <command-line>:
  lib/vdso/gettimeofday.c: In function 'vdso_calc_ns':
  lib/vdso/gettimeofday.c:11:33: error: 'U64_MAX' undeclared
     11 | # define VDSO_DELTA_MASK(vd)    U64_MAX
        |                                 ^~~~~~~

Use ULLONG_MAX instead which will work just as well and is in
include/vdso/limits.h.
