syscalls/fadvise: Fix regression

These test were disabled from execution without _FILE_OFFSET_BITS != 64
since their conversion into the new library. The problem is that we
didn't copied the original condition correctly. Originally the tests
were disabled in case of:

if ((_FILE_OFFSET_BITS != 64) && (__NR_fadvise64 == 0))

While after the change they were disabled in case of:

Now looking at the original condition the __NR_fadvise64 was never equal
to 0, since the original tests included lapi/syscalls.h which defines
fallback definitions with value -1. So either had the __NR_fadvise64
correct value or was set to -1.

All in all looking at the code it does not make sense to disable these
tests anyway, so this commit just removes the ifdefs.
