tls: make tls tests great again

* TLS tests were "empty" because nothing was setting the following variables:

  * USE_TLS
  * HAVE___THREAD
  * HAVE_TLS_MODEL_ATTRIBUTE

All toolchains supported by uClibc-ng today do support both NPTL threads and TLS.
All ports also define HAVE_TLS_MODEL_ATTRIBUTE except alpha.

* 3 tests (tst-tls6 / tst-tls7 / tst-tls8) were peeking into internal/private
data structures from libc, which is not possible anymore since libc and
tests are now split into 2 git repositories.

This commit fixes those 2 issues so that TLS tests can be run again.
