0fe1f070fa Fix getauxval() in glibc-compatibility 
getauxval() from glibc-compatibility did not work always correctly:

- it does not work after setenv(), and this breaks vsyscalls,
  like sched_getcpu() [1] (and BaseDaemon.cpp always set TZ if timezone
  is defined, which is true for CI [2]).

  [1]: https://bugzilla.redhat.com/show_bug.cgi?id=1163404
  [2]: https://github.com/ClickHouse/ClickHouse/pull/32928#issuecomment-1015762717

- another think that is definitely broken is LSan (Leak Sanitizer), it
  relies on worked getauxval() but it does not work if __environ is not
  initialized yet (there is even a commit about this).

  And because of, at least, one leak had been introduced [3]:

    [3]: https://github.com/ClickHouse/ClickHouse/pull/33840

Fix this by using /proc/self/auxv.

And let's see how many issues will LSan find...

I've verified this patch manually by printing AT_BASE and compared it
with output of LD_SHOW_AUXV.
